Since I dont know much about the whole tuning process I wanted to post and see what others think about my situation. As some of you know I have a tune from NPG that ran my stock uim on my full 3L just fine, now I just put my ST220 uim and 65mm TB on and thats where the problems begin.
I am on my third new tune from Joey since putting the new intake on, and it still runs like poop. It struggles in low RPMs but after 4kish it has no problems pulling like a freight train. When cruising at low rpms it skips and misses soo bad sometimes that my serp belt slips and squeels all the time not to mention the car jerking like crazy. My air fuel gauge is kinda alll over the place. Surges when idling, and likes to die sometimes as well.
As much as I dont want to fork out another $500 on a dyno tune I feel like I just need to in order to get it runnning right. This whole datalogging and test driving around to see if anything has changed is wearing me and the car out, as I am starting to hear strange noises probably from the constant jerky and crappy powerband. And I dont think Joey has ever tuned an ST220, and half the time he doesnt remember why hes doing the tune or forgets that I sent him datalogs. So what should I do my fellow CEG'rs?
