Downpipes Problems
 

I just put the milltek downpipes on my car. Sounds great. The problem is that once the car warms up I lose alot of boost. I brought my car to the dealer and they changed the wastegate hoses because one of them had a hole in it. They wiped the codes out. Then after a few minutes the power cut out again. I changed CPU's and the same problem occured. One tech at the dealer told that the CPU has to be remapped to eliminate this problem. Is that true, if so what do I do.

I think you need software specific to having downpipes (don't know details though)

Ask Strat, not here:)

Keep us updated on what happens, Bob said there should be any problems with just exhaust and DP
