Turbo M20B25 Bucks at WOT

[greenguy103]

Hey guys,

When I give full throttle to my car the boost builds, but when I am wide open throttle the car will buck and stutter. It will do it a few times then continue to accelerate. Not sure if it might be an internal wastegate issue or anything. Just looking for some help.

Thanks Yall!

Hey mate,
I am having the same issue. I checked my CPS and the gap was way off. I would start there. Also check your TPS.

What is your tuning like?

[Kershaw]

Yeah, what sort of engine management are you running? Definitely check the CPS gap.

...yeah, without more details on how you are set up, it's kind of hard to diagnose over the internets.

Are you running any sort of WBo2 sensor to see what is going on with fuelling?
