PCM Code

[X JBM X]

BUMP! I want to order but won't have time to get to a code reader as soon as I'd like.

I have a 99.5 w/ a build date of 3/99 and my PCM code is NVK3, if it helps?

[X JBM X]

I appreciate that...I'm not sure it helps any though...

I may just wait until I can have the code read. That way I have a 100% for sure answer.

Ugh. Took the PCM out of the truck, and read the code. Order form sent in!!

[hayjayhorses]

did you get your chip yet?

[X JBM X]

Yep, got the chip and installed it yesterday before my 300 mile road trip.

The power is amazing!

The shifting under heavier throttle is awesome, but under light throttle not so much. It seems to be "over-clutching" - if you think about it like a manual, in between gears, if you give the truck too much throttle and then let the clutch out it does that forward buck before slowing down to catch up with itself.

I'm assuming that's not normal, but could someone please confirm that? It happens in both 80dd and 120r.

Which shift does it occur in?

I know your order form said that there weren't any transmission modifications but are you sure? Could a previous owner have done something to it?

The tunes you have are very similar to all of the PMT1 tunes that Bill has put out for quite a few months (and it's the most-used 7.3L platform we sell). I have looked at the programs and can find nothing askew with them.

Which shift (1-2, 2-3, 3TCC apply, or 3-4)? I'm wondering if you are feeling the 3rd gear torque converter clutch apply at approximately 35 MPH. Your NVK2 didn't do that under normal driving.
