Our engine calibrator just spent a day tuning the software in an otherwise stock L99 automatic. The performance increase in the response and shifts of the transmission are very impressive. I am willing to offer this upgrade to any L99 owner at no cost up front. Send us your computer, we re-program it and overnite it back to you. If you like it, THEN you pay us. If you are not totally impressed then send it back and we will program it back to stock. It is that good. I will start a new thread about this.
We can tune the ECM for stock, cold air, catback, headers, supercharger or any combination of these mods. But it is very impressive on an otherwise stock L99 Camaro!
