Has anyone used the DHP 1.5 Starter Bin to tune their 2004+ Transmission? what do you think?

I used dhp for a little while and from that little while I would highly recommend get rid of it and get hptuners. DHP changes your VCM ID to 86 and after awhile the pcm wont start (I had to reprogram my whole pcm sunday night with hptuners because of this) and I've had dhp fry a pcm.

My tranny tune is still basically the 1.5 starter with a few changes that Overkill sent me.

I've been tuning with my DHP since 2005 with no issues.

Some have had good success with DHP but myself and others have not and I would hate for someone to have to deal with what I have.

the starter 1.5 is a good starting point but i am having a problem with the engine losing power about 100-200 RPMs before the shift. Those last few RPMs it feels like the tranny slipping and the engine is going no where. under a slow throttle into the pedal the problem doest exist - strictly a tranny tuning issue. is this something caused by higher shift points? still on stock pulley at the moment but have headers and Wizaired CAI

sounds like the torque converter is enganging/slipping and bogging the car down. Does it happen a lot when going up a hill @ low throttle positions? then you gradually give it more throttle and the converter will lock and rpm's will rise kinda like it's shifting to a lower gear.
Go into tiny tuner and increase "TCC pressure apply rate" by %10 intervals until it's to your liking :grin: that should fix it.
