hey guys, i recently had my car verso tuned and ran sweet for the first few days. Then after that it started playing around when it been sitting for a few hours, jump in it and let it warm up again then coming onto boost the car jerks real bad then hit boost and its fine. Once i have been driving it for a while it settles down but can feel it hesitate a little when spooling then fine? Also it back fires alot more then it use to aswell.

Could this be a fuel delivery problem or is it possible for the tune to reverse it self?
The car is a 01wrx mods are aps cai, gfb bov, warbro 500hp fuel pump, silicon intake and verso tune.

We are flat out at work so i can't get the chance to take it to asg.
Thanks

Matt

call ASG

Impossible to say....
However, your 'tune' hasn't changed. Something else has. I'd start by looking at plugs, leads, fuel, and vacuum lines.
