^^^^ Wow Defiant pretty much described every issue I currently have.

I have ECUTEK so hopefully Tony can solve the problems for me as I don't feel I should have to run a Cobb AP to do it. I am guessing he was able to do it with the Cobb AP because he has more experience tuning with that vs ECUTEK.

Well this was gone right after Tony tuned my car on the 28th, but it came back. I tried adjusting my APS valve and checked all the FMIC hoses for leaks. I've got the crazy idle again and the shudder/bucking is back.

After re-reading your post, it seems I need to switch to Cobb to fix it? I shouldn't have to switch EM to fix something like this. I doubt it is a limitation of ECUTEK, possibly the tuner? IE Tony is a better Cobb tuner than ECUTEK tuner perhaps?

I have the same turbo AND the same injectors AND Tony from XX tuning tuned my car AND I have the same idle problem that 1FastSti has.

I have seen the Perrin injectors being off from each other as much as 6-9% in flow. Not a good thing at all.

Not sure how this relates as 1FastSTi and I both have the Power Enterprise injectors not Perrin

Whoops, could have sworn I read Perrin injectors in his mod list, Sorry.
