With up to 550 HP and 511 FT-LBS of torque, this upgrade transforms your car into a performance powerhouse, delivering exhilarating power and unmatched driving excitement.\u003c\/p\u003e\n\u003cp\u003ePower. Precision. Protection.\u003cbr\u003eOur new ECU software is the result of months of meticulous engineering and real-world testing, far surpassing the typical aftermarket solution. By equipping our development vehicles with high-speed data loggers, turbo shaft speed sensors, thermocouples, and other precision instruments, we fine-tuned hundreds of parameters and corrected countless protection models across multiple octanes to achieve flawless performance, enhanced safety, and unmatched reliability. We're so confident in its reliability that we even offer an optional factory term-limit matching limited powertrain warranty with APR Plus!\u003c\/p\u003e\n\u003cp\u003eWhat does that mean for you?\u003cbr\u003eIt means blistering acceleration with gains of up to +119 AWHP and +135 AWFT-LBS over stock with just tuning alone, and even more with our hardware upgrades! This tuning package delivers a rush of power that transforms your driving experience. With the right surface prep and tires this is a sub 3 second 0-60 car capable of 10 second quarter mile passes that will drop your stomach and pin your back to your seat like never before! You'll enjoy smooth, linear throttle response and a torque curve that feels endless, providing relentless pull across the rev range. Race-proven features like brake boosting and speed limiter removal unlock new levels of control-perfect for track days or spirited driving. All of this is backed by advanced safety routines that ensure your engine remains protected, even under the most demanding conditions.\u003c\/p\u003e\n\u003cp\u003ePerformance without compromise\u003cbr\u003eOur ECU upgrade includes advanced safety features that go above and beyond by correcting modeled sensor data within the ECU and enabling and calibrating new protection routines. We've optimized turbocharger protection by monitoring shaft speed and respecting overspinning limits, excessive exhaust backpressure, and unstable pressure ratios. Low-speed pre-ignition (LSPI) protection prevents engine damage in high gears. Thermal management actively reduces power to prevent overheating of critical components and reduces power until your oil reaches the proper temperature. Fuel system optimization ensures safe, reliable operation within critical fueling limits. The result? Massive power gains with the confidence that your engine and drivetrain are protected for the long haul.\u003c\/p\u003e\n\u003cp\u003eEnhanced Driving Experience\u003cbr\u003eWe didn't stop at raw power-APR's ECU upgrade enhances every aspect of your driving experience. To truly experience the sound of this engine we open the exhaust valves 100% above 3,000 RPM for sound and power delivery. Furthermore we've calibrated a new light exhaust crackle that's similar to previous factory RS3 models. In park we additionally raised the standing rev limiter to 5,500 RPM, open the valves 100% during revving, and added the exhaust crackle. \u003c\/p\u003e\n\u003cp\u003eFurthermore, we've added left-foot braking and brake boosting for greater control on and off the track, while the speed limiter removal unleashes your car's full top-speed potential. The Auto Start\/Stop memory ensures your preferred setting is always ready, putting you in control every time you start the car. Finally, we've recalibrated the boost, power and torque gauges so you can see the full range present at higher power levels!\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch3\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003ePower Gains: Up to 550 HP \/ 511 FT-LBS (+153 AWHP \/ +141 AWFT-LBS)\u003c\/li\u003e\n\u003cli\u003eIncludes 5 Fuel Grade Tunes: 91 AKI (95 RON), 93 AKI (98 RON), 98 AKI (102 RON), 100 AKI (104 RON), 104 AKI (108 RON), and E60-E85 (no hardware required)\u003c\/li\u003e\n\u003cli\u003eMultiple Performance Stages: Specific tunes for use with stock and modified hardware\u003c\/li\u003e\n\u003cli\u003eAPR Plus: 91 AKI Stage 1 with an optional factory-matching limited powertrain warranty\u003c\/li\u003e\n\u003cli\u003eEnhanced Features: Enhanced exhaust note\/crackle with fully open valves, increased standing RPM limiter with exhaust crackle and fully opened valves, speed limiter removal, Auto Start\/Stop memory, left-foot brake boosting, linear throttle mapping, and unc\u003c\/li\u003e\n\u003cli\u003eAdvanced Safety Protection Routines: LSPI\/knock protection, thermal management, turbo\/pressure quotients, and fuel system protection\u003c\/li\u003e\n\u003cli\u003eECU Swap: Our software installs to an unlocked ECU\u003c\/li\u003e\n\u003cli\u003eLifetime Updates: Continuous improvements and support\u003c\/li\u003e\n\u003cli\u003eSupports Bolt-On Mods: Adding most hardware upgrades increases power and maximize performance with our software stages\u003c\/li\u003e\n\u003cli\u003eNo TCU Required: Full torque is unlocked without requiring a TCU upgrade\u003c\/li\u003e\n\u003cli\u003eSoftware 30-Day Money-Back Guarantee\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eImportant Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cdiv style=\"max-height: 576px; opacity: 1; padding-bottom: 30px;\" class=\"row-contents active expanded\"\u003e\n\u003cdiv class=\"widget_info\"\u003e\n\u003cdiv class=\"widget_text\"\u003e\u003cstrong\u003e\u003ca title=\"View Important SFD Unlock Guide\" rel=\"noopener\" href=\"https:\/\/www.goapr.com\/sfd\/\" class=\"tech_resource_widget_link\" target=\"_blank\"\u003eSFD Unlock Guide\u003c\/a\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"widget_info\"\u003e\n\u003cdiv class=\"tech_icons fas fa-info-circle fa-2x\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text\"\u003e\u003cstrong\u003e\u003ca title=\"View Important fuel quality information\" rel=\"noopener\" href=\"https:\/\/www.goapr.com\/support\/fuel_guide\/\" class=\"tech_resource_widget_link\" target=\"_blank\"\u003eFuel quality information\u003c\/a\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"widget_info\"\u003e\n\u003cdiv class=\"tech_icons fas fa-info-circle fa-2x\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text\"\u003e\u003cstrong\u003e\u003ca title=\"View Find your boxcode and revision\" rel=\"noopener\" href=\"https:\/\/www.goapr.com\/support\/ecu_box_code\/\" class=\"tech_resource_widget_link\" target=\"_blank\"\u003eFind your boxcode and revision\u003c\/a\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"widget_info\"\u003e\n\u003cdiv class=\"tech_icons fas fa-info-circle fa-2x\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text\"\u003e\u003cstrong\u003e\u003ca title=\"View APR Plus Warranty Booklet\" rel=\"noopener\" href=\"https:\/\/documents.goapr.com\/customer_warranty_booklet.pdf\" class=\"tech_resource_widget_link\" target=\"_blank\"\u003eAPR Plus Warranty Booklet\u003c\/a\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"widget_info\"\u003e\n\u003cdiv class=\"tech_icons fas fa-exclamation-triangle fa-2x\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch3 class=\"tech_icons fas fa-exclamation-triangle fa-2x\"\u003e\u003cstrong\u003eECU Unlock Information and Procedure\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cdiv class=\"widget_text installation_notes product_info\"\u003e\u003cstrong\u003e*An ECU unlock is required to install this software*\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text installation_notes product_info\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text installation_notes product_info\"\u003e\u003cstrong\u003eTo unlock your ECU:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text installation_notes product_info\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"widget_text installation_notes product_info\"\u003e1.

Follow our fuel guide, particularly for race fuel and Ethanol. Dyno results are for reference only and will vary due to vehicle condition, setup, dyno type, environmental factors, and fuel quality. North America uses the Anti-Knock Index (AKI) (RON+MON)\/2, while the Rest of the World (ROW) uses RON. Each vehicle's year, make, and model may have multiple engine or transmission controller software part numbers (\"box codes\") with unique revisions. Manufacturers release updates that alter these codes, which can only be verified by scanning the controller. Some stages, octane levels, or features may not be available for specific box codes. Our website provides a general guide by Year, Make, and Model, but you can request unavailable software.
