Went to the track last night CEL came on

[JMstang7]

I went to the track last night on my second run my car threw 3 codes p0354 p0355 and p0358. Something to do with coil packs I belive. The car isnt missing drove it home fine. But when I drove it down the track in 4th gear at 3500rpm it would just fall on its face. Do I need aftermarket coil packs? and the car is running a little lean should I need 24LB injectors. I am not sure just with the bolt ons I have I would think the stock coils and injectors would be ok. But i am kinda new to this.

Canned Tune would be my guess

i would say its far from needing bigger injectors judging my your mods. if i were to guess, id say its something in your tune

Maybe I'm not that big into modding a 2v...but if that's all you have done and you're maxing out the stock injectors I'm glad I have these 39#s sitting here for Tiffeny's car...

I'm sure its the canned tune he's using. Those are useless. One size does not fit all when it comes to tunes as you know.

try loading the stock tune and see how it goes, might run faster and not throw codes
