I'm still working on the before/after video of the exhaust upgrade, but I'll update this post when I get it done and uploaded.

Initial impression - HOLY CRAP what an upgrade. Sounds amazing, deep and mellow. The difference in throttle response and power makes it 100% worthwhile.

So far we've also done the dual thermostat upgrade, with the 130pgh waterpump, and a Mishimoto all-aluminum radiator.

Today we're going to be installing gauges (EGT/Boost/Trans Temp), A-pillar pod for the gauges, and installing the B&M 70274 for the transmission. Should be fun!

i got a heath diesel EPROM from a suburban if you want to make me an offer for it

Sounds good:tu:

Which year and do you have a part number? Rumor has it that there are different chips for different pumps...

Came out of a 95 i have to get the part numbers off of it, but i put it in my buddy's 94 worked in his truck too, im not sure if it will work in all of them or not.

Yes, he's interested and asking for the numbers!
