Well where do I start. I just had my motor rebuilt due to a busted piston, bored 0.30, forged rods and pistons. After install it had a really rough idle so I threw my SCT programer on it and retuned it back to the tune it was running before rebuild. It ran fine a little hesitant but I figured it was because of the fresh build the motor being real tight. Well day by day its getting worse, I only have 100 miles on the motor, It seems like its starving for air or fuel I dont know which. At a Idle it goes between 740 rpms and 810, I have a digital tac. When you give it about 30% throttle it hesitates then I feel it get its power, but cruising at a solid speed, if i let off the gas it give it gas again to maintain its speed it seems like its choking. I have checked for vacum leaks i cant find any, I have a exhaust leak on my headers just need to tighten it, dont think that would be cause it to run like it is tho. I have duel cobra fuel pumps, 42lb injectors, its intercooled, and tons of other mods. Any advice would be great guys.
