hello first of all I am very new to tuning and just got my HP tuner a few weeks ago. Ive disconnected my MAF and car starts and immediately stalls.IE will not run in speed density. A local tune shop put what I believe to be an off the shelf tune in it for an ls1. I think injector size is wrong, amongst other things. I learned also the tune they put in would not support the ls3 2 bar map that was installed so I changed it back to a ls1 1bar style. Any input would be greatly appreciated!
