im only throwing a iac code,and when i use a chipped pr4(dumps alot of fuel so i dont like it)it drives fine
but if i use a pm6 it bogs down when i accelerate really fast

and i bog down if i floor it,but this only happens if im running on a pm6 or ps9 ecu,the chipped pr4 im on now wont do it but it gives me bad gas mileage.

so anything you know of that can make a car bog down let me know
