I built a 11.0 to 1 forged ls1 with patriot ls6 cnc heads and had it tuned running into some issues at idle. It's surging at idle and gets worse when Ac is engaged my bank to bank trims are also off but 42lb injectors bench flowed good and replaced front o2 s and still seem to be out of whack. Suggestions please

Thought maybe it was the converter but it's seems to be stalling correctly around 23 to 2500
