Okay now the evo9 issue that I had that cut boost here's what I did. Now first I thought it was the tune checked the tune same result with the car running lean and cutting boost.

Now we tried taking the tune and reflashing it to stock we got the same results. Then we tried putting the flash on the car then we tried to check the car for codes the tech used a snap-on scanner the real expensive one the issue came up with the mad sensor. All that time the issue was with the mad sensor s.o.b all that time and frustration over one sensor replaced it with a stock replacement the car stopped running piggy rich at idle.

The next issue with the mad sensor was that even though it was plugged in we reset the code and it came right back. At least its confirmed and now I'm boosting 25 spike 22 red-line.

 

Glad you found the problem.
