PHP chip problem??
When I am in my two hottest tunes accelerating hard it feels like my truck just stops pulling hard once it gets up to about 65mph or so.
Doing the same thing with my manul TC lock switch on it pulls hard as long as I have my foot in it.
Is there something wrong with my chip programming for the transmission? The TC seems to be slipping when I let the tranny do it's own thing with the chip...

My next suggestion is to run it up with your torque converter apply switch off, let it do it's "topping out" thing and then while still under load, flip the switch on and let us know what the RPM does.

Mine has that feeling on stock sticks espescially on the 140hp tune. My pump levels at 2000 psi though. After a certain point it just feels like it quits pulling. But I have a 5 spd so...

If your rpms are going up and not increasing speed you got problems. Sounds like tranny slipping to me. Hope that's not the issue.

Havn't gotten a chance to try it again. I'll check the boost next time and try switching the TC on part way through.
I really hope it isn't the trans slipping. It only has 20k on it, factory reman. Another reason why I can't wait to put the ZF5 in it.
