Thread: 9.11 lbs of boost with stock pulley?

I'm surprised that you haven't thrown 3 pistons straight out of the hood man. Also something to consider, you could go get it tuned by zzperformance.com, they are the best tuners out there. Or you can go to INTENSE-RACING.COM They are the leaders in 3800 specialties, they should be able to take care of you!

so your answer is either to get it tuned by zzp or get a smaller than stock pulley? Here is an idea: find out what is causing the knock and fix it. There is no way short of a terrible tune( i.e. advancing the timing through the roof) that you should have that much knock with a stock pulley. Find what is causing the knock(or if a sensor is bad) and fix it. And for the record zzp might do ok with custom tunes, but they have been known to blow motors with their canned tunes for our cars, so I would stay far away from them for tunes. They just cut it too close to be safe, IMO...
