Red line mod complete, new logs have been sent to you Tugly. I have brand new boots on the tops of the IC pipes, they are 3" hump couplers. Bottoms are factory still. I can order new bottoms then pull all the pipes and clean them via a suggestion on how to do so.
I have seen way many different wheels beling sold. Always wanted one but was never sure what one was the right to go with. I have never experienced turbo surge, and see thats what one is made for. What about the others? What are reasoning for buying them? Do they push more air? Or? And have any been compared with real data and have supporing evidence backing them?

I just reviewed the new data, and we're sneaking up on this problem. The MAP peaks at 28.6 PSI, no matter what tune - but the EBP can peak between 30 PSI for stock and 50 PSI on a 100HP tune. This screams out that he has a boost fooler unbeknownst to him. This happened to me when I first bought Stinky. Most of us are familiar with the fooler that goes on the MAP tube... but I suspect this one is hidden from him - in the form of a what looks to be a wire from the MAP signal wire to ground.
I need confirmation before I go deeper into that.

Mine is stock and the whole CAC system is shiny and lubed. If you revert back now, you may get some sludge if the system isn't cleaned first.
Something is going on with your MAP - because it flatlines while the EBP just keeps climbing in the bigger tunes. I still think you have a boost fooler, or your tune is limiting the MAP reading.

Tomorrow in the day light i will check again, i REALLY do not think there is anything there, everything looked factory... is there any way i could test the system to see if we can narrow down the problem far enough to find a source?

Key on, engine off. Hook regulated shop air up to the MAP line. Increase the pressure from zero up to 40 and monitor MAP pressure. If it stops rising in the same place with 40 psi of shop air applied, you either have a bad MAP sensor, or something fooling something, somewhere, somehow.
