So I'm running a dob setup and I got it tuned by blow by racing. I've spent over a grand there trying to get it running right. It's been a few month and from day 1 when I got it back my car sputters when I hold the rpms 2800+rpm range in 3rd , 4th gear and had a little in 5th gear recently but haven't had really any issues in that gear normally. It's kinda consistent. I've replaced my module for my fuel pump and I have the one they gave me and gave them the one crown sent me as a replacement cause that's how they wanted to do the deal and I figured out my fuel gauge problem after I tried having them fix it and they couldn't (paid them to fix). But I've tried to datalog for them and they got a virus and lost my info so now need to fill out paper work again. So before I go through all that and have them go through all my wiring because that's what they are saying will have to be done cause they don't know why it's doing it. They also said it could be the tps. So I'm coming here and seeing what you guys think it might be before I buy a new one of those to and see if that fixes it or have them go through the wiring. But car runs fine in WOT.
