Tuner for 6.7 cummins

[Arrowthreat]

I say start calling some tuners and ask questions. I wore the folks at ppei out for weeks on the phone before I ordered. There are lots of great tuners out there.

Do you have a standard or auto trans?
6 speed you can throw a clutch in it and crank it up with the csp5.
68RFE auto I would stick to a 30 or 60 horse tune with trans tuning. 5th and 6th gear clutch packs are weak. Anybody running a high hp tune on stock 68 tuned of not is on borrowed time.

I just picked up the phone and told a few efi tuners my needs. That's the best recommendation I can give you. Also 6.7s like to lift the head if timing is added and you don't wait for engine to come up to temp. Me I wanted deletes, mpg and longevity.

I have an automatic. I called multiple places and ended up going with Robert Ivey out of Kingsland. I have a few buddies who swear by his tunes. I called his shop this morning and I was able to speak with him directly. Since I'm just looking for better mileage, I'm going with the 60hp tow tune. Thanks again for yall's help.
