Hey guys, so I’m still in the process of tuning the Mach, but running into some issues. Car is running a ysi with a 2.95 pulley and a 15% crank pulley. Had some belt slip issues and just put the tightest belt I could get on it, figured it would get rid of what was going on, but it didn’t.
So the car runs great, 1st gear and 2nd gear are strong and it’s hitting just about 20 lbs of boost in 2nd. Then I shift to 3rd and I’ll be lucky to get it to about 15lbs. Car just feels like it’s trying to go, but just won’t grab. I’ve tested the intake, intercooler and pretty much everything else for a vacuum leak or somewhere it could be bleeding boost off but everything has held over 20lbs. Only thing that leaks just barely is the egr valve, but even when it was pressurized to 25lbs it was only dropping about a hundredth of a lb of boost per second.
Anyone else ever have this issue?
