When driving off the line WOt my car is great until 5000 rpm when it seems like the fuel is cutting out or the engine is chugging. But when I am just driving along at 5000 rpm and then hit the gas the 2nd turbo kicks in. I have brand new twin turbos on the 93. prior to the New turbos I did the silicone hoses. I have the M2 intercooler and intake along with downpipe and ohter stuff. I don't know what the problem is. I think it may be the computer cutting fuel but my fuel pressure gauge looks good. My Air/fuel also is at rich. I have not had it checked out at a real mechanic yet. I took it to Mazda and the were idiots. The said that the throttle stick(it never has) and that had NO clue about my intercooler. Any ideas would help.

 

Sorry about the MANY typos. I was in a big hurry posting that message.
