[QUOTE="LugNutLX, post: 10813161, member: 123374"] Long story short I bought a car with a blown engine that had a supercharger on it so I put a stock engine in and it ran but had no power. I realized it had a chip in it so I pulled it and it ran even worse. I found out the chip was tuned for 39lb inj's and I had 24's. I put a set of 39's on it that were my buddies and the car ran great. So I had the chip burned to stock and it seems a little low on power and seems to have a slight miss all the time and has a different tone than it did previously. I had the chip burned at alternative auto in michigan and Lidio said that the ecu was probably flashed before so he flashed the chip with a stock tune. To me it sounds like the ecu has an issue. I did have a check engine light and its for an O2 sensor bank 2 sensor one but I didnt think that would cause this issue because it does it on cold starts and at full throttle. No codes for misfire either. Im very frustrated :cuss: and cant think what else to try. Any help is greatly appreciated. [/QUOTE]
