The GTE pulled like a train to the limiter, this GSi is a little reluctant.
You think a decent service & K&N panel filter would help this?
Engine is a goodun, just think it needs some help.
Haven't looked to see if there is a CAT on there, if so that's coming off. I know an aftermarket exhaust would help but not doing that yet, unless a system comes up cheap.
Throttle body mod is on the way too this might be nice.
Suppose injector cleaning might be an idea as well.
