So is that good or bad? I mean I bought the car this way because I lack the time and desire to gamble with tuning it myself or trying to find someone qualified. This was before I learned of the power of this forum. I had a real bad experience with a supercharged GTA that had an aftermarket ECU and shops from NJ to CA trying to tune it properly. Sold the car after getting it done in CA because I figured it anything goes wrong, I'm screwed. Can I still put it on a dyno with the JWT ECU? just to get an idea where she's at as is.
