I have a trinity and I'm going to put a tune on my 03 neon srt4, I was curious if its ok to use the tune with the 2003 stock injectors. Im new to the tune world. To my knowledge the car is stock except CIA, AGP waste gate, 3" catless turbo back exhaust, and engine mounts. Any thoughts?

Hmm i didn't see that coming, i have no idea what spring is in there either. I really only bought it cause I've been getting the notorious p1188 and the occasional p0234. I found a tiny vac leak and fixed it but i was told the tool is a must for these cars plus it'd help with the CEL. Thanks for the quick reply by the way.

Does it work with the 8LB spring option I saw on the WG on modern performance https://www.modernperformance.com/produ ... eactuators

I just went ahead and bought a 8lb spring for the waste gate, I hope this works. I'm waiting to tune til I put it in and reconnect the vacuum lines to the solenoid.

I have an 04 srt-4 and put the Diablo 93 tune on it and now it won't go over 10lbs of boost. Can anyone tell me why? And I have an aem wide band but it always reads lean unless it's when I first start it up. I'm new to the srt-4 so please help
