One of my friends asked me if i was able to check the tune on his car because its having problems whit idle, as im on the learning curve i really dont know how to identify the problem on the tune, i logged the car to show how it is working and i atached the tune too.. the car has a procharger whit 10-11 lbs, it is a lsx 417 engine, has cam, intake manifold and 102 tb. the car runs right in mid and WOT but in idle it will revv up and down, we already search for vacuum problems but everything looks ok, so if anybody can help me to find if the problem is on the tune that will be great..!!
