I have had this problem since last year. With the car in neuteral, reving the motor, as soon as I let off the gas there are a few small pops through the exhaust. The wideband shows +-1 percent correction, air fuel around 13.5/14.0. Last year, I had a few instances were I would down shift (my wastegate is vented to atmosphere) and a big flame would shoot out the waste gate, followed by a big bang
As for the down shift goes, there is just about a back fire everytime
The motor I have in now is brand new, rings, valvetrain(swapped to solid roller), etc. This has only been a problem since the speed pro swap, any conclusions to this problem
Anything you can think, shoot my way
