We know purchasing the proper tune can be a challange, we have the ultimate tune and package for your GR Supra. This is the last and only tune you will need, of coarse you can always retune and upgrade for more. Speed Industry ECUtek A90 Supra tunes have been developed in house for consistent and reliable power increase for your Supra. Our tunes were developed with our 20+ year background in engine calibration to provide stock drivability with the extra power and torque when you want it.  Power delivery is smooth and predictable for track and street use. Tunes can be calibrated for 91/93 octane pump gas or E30/E50 Ethanol blends.  Multiple tunes can be purchased at the time of original purchase or later at discounted rate(s).  All tunes include datalogging help and review to make sure your car is runnning properly and revisions will be sent

Our maps have been shown to produce a smooth +/- 80 WHP and +/- 120 WTQ on Pump Gas and even more gains on Ethanol Blends
