does any one know which is better for an evo 8 on ecu flash on a green turbo , pump and vp , i want to know which one i should go with i have both i just want to know which is better and why ????

 

When running high boost on the profec I wa running into big problems trying to get every last bit out of the stock turbo, would rally only allow 25psi peak when banging through the gears or else it would fluctuate horribly if I turned it up more.I tried everything but the jdm BOV leaking a bit may have had something to do with it. Switched to a MBC now and spoolup is definitely better with none of the profec fighting to try and slow the boost when it gets near the desired level..I tried EVERYTHING on the profec to eliminate the issues..Worked decent on a 3rd or 4th gear pull but at the track it was a hinderance.

 

I had a MBC I made out of parts from home depot years ago and used on several of my turbo cars. I bought the greddy profec B spec II and the boost response/hold was exactly the same.

 

or you could try ECU boost control with a GM 3 port
