    Did Buddy tune it on a dyno or just street driving? I should of had him tune my NA MPI. I too get the shock when I touch the frame and now there's a problem with my charging system. Not sure if all that is related though. I am going turbo real soon and I am going to see if I can have Buddy tune it and maybe ask Nick if he can install the turbo module as well.

    That sucks you weren't happy, but O2 tuning is very easy to do and he probably just wanted to be safe and not go above 10psi, I don't know. Yes, Dana's way works, but you are not utilizing the stock injectors to there fullest. With the O2 tuning, you don't need an O2 clamp, you are controlling it. I ran mine like this for some time and made the same power as controlling the MAF. The fact is the all the way's work, it's just about user prefference.

    I tried it with a 3bar MAP and it didn't have fine enough resolution for me. I actually like the MAF control better because it gave better fine resolution. Perhaps a 2bar would have worked well, I may try it someday. Oh, O2 tuning uses negative numbers, so if you had those and he was like WTF, that's why.

    i coulda sworn the main reason why there were so many issues with the MPI were because you cannot control the stock injectors (if you can it's still iffy). Correct me if i'm wrong please. I'm trying to get an edujamacation on this

    Sure it works, and it works well. I have ONLY ran my car controlling the stock injectors via the MAF or the O2. I have tuned cars that ran well like this also.

    he street tunes it, but his street tune is very close to what a dyno tune would produce.

    Hey Tim, I am sure if you or anyone on this forum spends $800 you would expect to see GAINS. Not cel or crapy tune... But dude all I want to do is write my review and what happened to me so I can save another forum member from loosing money. I thought we are on here to help each other out with problems and not rip each other off.

    well one exemple of it being iffy is at idle, my car will run at ~ 15.2 to 15.8 AFR no matter what i set the analog number to. it's like if the stock ECU keeps adjusting the stock injectors to get the AFR ratio it wants no matter what the mpi is set to ... i can drown the thing with the extra injectors though if i want. but anyway, things like that make me feel like i'm not in control at all.

    but it still works well for me so i'm still happy
