most motors make the most power 500 to 1500 below redline.. so why put the WOT shift so close to redline.. You drag racing this truck or driving it in traffic?

The Predator is very good, especially if you have internal mods like heads, cam, etc. I love my Superchips Flashpaq. IMHO it is the best for bolt-on type mods. The Flashpaq model 3865 is going to have transmission tuning features. The guys at Superchips have really done a great job with this. Part of it will be setting up and down shifts at part throttle and WOT along with reducing or completely eliminating torque control. The other guys I know who are beta testing the 3865 transmission stuff say it is fantastic and really makes a huge difference. I'm looking forward to my part of the testing.

What they don't realize is that by the time the transmission control module makes the gear change, they are up against the rev limiter and the engine is cutting out...creating multiple, high level torque shocks to the transmission and maxing out line pressures.

The best way to set shift points at WOT with a Predator is to be at least 200 RPM below redline, then test. If you are still hitting the rev limiter, back off in 50 rpm increments. The reason it hits the limiter is that it takes a second or two for the TCM to signal a shift and by then, with the shift point set too close to the rev limit, it's already past redline before it shifts. Ya gotta give it a little room to work.
That isn't the reason at all, I had a diablo predator and I have an '04 there is no trans support for the '04's. Yet when installed on my truck the transmission started to act up with erratic shifts and would clunk going into drive bad. There had to be something within the way the tuner wrote the tune to the PCM or something in the tune itself. I think Diablo has since fixed the problem and I haven't heard of any trans problems in awhile. But as hemibyrd posted above Superchips is by far the best if you are not in need of custom tuning there trans control is far Superior to anyone else's and will be for along time to come.

Just thought I'd share what one of the beta testers for the Flashpaq 3865 said about the tranny tuning.
Quote:
I'm running the same shift schedule, and it is amazing! The great thing about the reduced TM, is not that the shifts are "neck-snapping" firm, it's the fact that the shifts are VERY fast. The truck literally keeps pulling through the shift, which is what we all want. You no longer have the "sling-shot" shift where the truck has a momentary pause before snapping into the next gear; this is most notable under WOT shifts.
