Hi I can't seem to figure this problem I have 2011 Maggie Camaro ss with 495 whp and as soon as vaccum changes to boost, car heaitates, studders, and backfiring occurs I've taken the car to 3 different tuners in Los angeles and they're all scratching their heads. I suggested using a 3 bar map but they said car doesn't require it, It only happens at WOT, not when when I progressively accelerate or if I accelerate to fast then it also occurs where car studers and I hear what I think is back fire. Please help if you've come across something like I'm open to any suggestions . I bought the car used with 9000 miles and it did come with x3 tuner and I'm desperate at this point And I don't know what to do thx I really appreciate your input on this

You need ID850 injectors and ZL-1 fuel pump and control module to support your build and not burn down your'e motor.

Power seem low for that boost and I would be very worried about injectors and fuel pump supplying enough fuel for that pulley
Also belt slip is a big problem without our supertenstioner below a 3.6 pulley.
