Custom ECU and transmission tuning for 2021-2025 GM full-size SUVs running the 5.3L (L84) or 6.2L (L87) V8 with the 10L80 10-speed automatic. We build a custom calibration for your truck - expect improved throttle response, smoother shifts, better part-throttle drivability, and 15-40 RWHP depending on modifications.
Supported vehicles: 2021-2025 Chevrolet Tahoe & Suburban, GMC Yukon / Yukon XL / Denali, and Cadillac Escalade / ESV.
Platform: these are GM Global B trucks running the E90 ECM and T93 TCM. The E90 is locked from the factory and must be unlocked before it can be tuned - that is included in your price. The T93 transmission controller unlocks free, so full transmission tuning (shift firmness, shift points, torque management, TCC) is included at no extra charge.
Choose your option: send in your ECM and we unlock and tune it, or buy an unlocked, tuned ECM from us. Both include engine and transmission tuning.
What we can adjust: AFM/DFM (cylinder deactivation) disable, VVT, fan on/off temps, speed limiter, torque management, axle ratio, tire size, WOT fueling and timing, shift points and firmness, and more. Tell us your goals and mod list on the order form.
Note: HP Tuners credits are required to license the vehicle for tuning and are additional (+ credits). We recommend 91+ octane for best results. Ship with your order number - see our How to Ship Your Module page.
