hotrod161, what have you done for your exhaust? Since you have a Cummins, I would straight pipe it if I was you (I'm a chevy man, but I love the sound of a straight piped Cummins). In all seriousness I have a 4" downpipe back dual exhaust from Flo Pro, with the cat removed. I don't have the gauges installed yet, but I assume a free flowing exhaust would help.

 

I have a 4" Banks turbo back, my 02 came catless from the factory...

I am contemplating tackling a swap to a dual exit setup without buying a whole new system. I have the 4" splitter, just need to get ahold of a driverside exit pipe and another 4-6" exhaust tip.

 

I have a 4" no cat to a magnaflo muffler its very loud. really dont want it any louder i do alot of freeway drivin and it gets on your nerves after a while. I guess im gettin old

 

More air is what you need. The 64 obviously isn't keeping up. You could try a larger single but twins would probably be a better move for overall driveability.

 

Yeah it's got to be in the tuning. I've seen as much as 25 psi of boost on the extreme level. Other than different tuners we have similar setups as far as exhaust goes. PPE makes some nice stuff.

 

Yeah I would have to think its tuning. I wish I could afford more of their stuff right now.

 

I think I'm gonna start saving for a tranny and EFI Live.
