I recently purchased a cat with tripple 2.5's (mid 90's) with brand new powerheads & new EFI boxes. I have slowly been breaking it & running it a range of RPM's. It is topping out at 6500 RPM's though, am I under-proped or is this setting from the factory for the break-in period?

Hey BamBam,go to screamandfly.com and there are plenty of OB guys that can help you. I've got tripps also but on a v-bottom,i've never had that problem,yet, good luck Tripps
