Great white........did you ever end up ordering the tune from heath? Ive been going back and forth with my 96 trying to decide if I should go with the towing tune or the performance version. Im a little concerned with high egt's with the performance tune as I tow heavy with the truck. I would like to get as much power out of the truck safely as possible.
I had heaths gl4 tune in my 95 and was very impressed.
Just curious if you ever ordered the tune and if so, any input on how you do or dont like it.
Thanks
Nick
I did.
What you need to do is call Heath and tell him how you use your truck. Then, he can come up with something that works for your intended useage.
A lot of guys come up with "I want high hp" or "I want the lockup do do this" and that's what they get.
More often than not, they find out what they
wanted is not quite what they
needed....
I told Heath my intended useage and then told him to do what's best for my uses. You have to defer to the experts in these cases unless you know exactly what to do to get what you want. Of course, if you could do that you wouldn't need them in the first place....
I ended up with a tune that was neither performance, nor towing nor daily use.
According to Heath, I got a tune they've been working on that is kind of an "all around" tune biased towards a daily driver with good egt control and "hill decent assist" (holds the converter in lockup until 40-45 mph). The shift points in teh 4l80e have also been modified. Basically, it holds the gear a little longer before upshifting, a common practice in performance tuning a transmission. Makes for less RPM droip in the upshift.
It's OK. One good thing I've noticed is that my occational "dead pedal" throttle feel is gone. No more sporatic loss of pedal response.
The truck isn't a hot rod, nor is it a towing beast. It doesn't feel like it lost 1500 lbs overnight nor does it feel like it will pull the Queen Mary up Rogers Pass.
What it is, is capable of hauling my 35 foot Travel trailer with good power and egt's and is a great all around daily driver. I can also hammer the throttle and not crack 1000F on the egts. Jury is out on the better MPG claims, the right foot is still gets a little carried away from time to time....
Even had a littel fun confusing the heck out of a new powerstroke driver the other day:

I had a few issues with shipping and billing, but that aside the PCM programming is pretty solid so far.
Is it all tune?
Dunno. I did the 4 inch exhaust just before, and water injection and turbo master at the same time as the pcm change. I threw a fluidampr in just for extra seasoning of the mix...
It's probably a combination of all these things, but I got what I was after so I'm satisfied with it.......for now.
