not sure but i have the newer version of overkills pcms in my 05 gp and tonight i lost all power it its throwing a code and said something on the dac about the throttle body. Has anyone else had this problem because i have had to put my stock one back until i figure it out and is there a warranty for the pcms?

when you say no power, you mean nothing works, no lights, radio, etc? or no power as in the car drives but is very slow?
I would: remove negative battery terminal, install overkill pcm, connect negative battery terminal. Turn key forward to "run" position. Plug in a scanner and check for codes, clear any codes then start the car.

How long have you had the PCM? I heard that "Overkill" Will has been hard to get ahold of for quite some time...

Post the code and description if you can!! It really helps to know what codes are present.

Lots questions need answers too, how long has the pcm been in your car? Did you just perform any maintenance? Did you just install anything recently?(other than the pcm, see question1) What warning came up on the DIC? Hard to help with just "and now the car is stuttering and seems to shift really hard also seems to be a problem with the pcm and i have no idea whats going on"

You need to contact Will about this, he should be able to help you out.

i emailed him not to long ago and got a reply within a few days. he got a new email address so that may have been part of the issue from before.

ive got an 05 overkill pcm in my 06 and every day or 2 when i turn the car on all the gauges dont work, messages on the little disply about... u just name it its there lol... i turn the car off for about a minute open the door to get it the power completely out... then turn it back on and she's alive again! overkill already replaced the pcm for me once... and he had no clue y its doin that.. and i didnt care :S
first time this happened to me was driving on the highway... it was a 450km drive with no life between the 2 cities! i was doin like 130 and all giages shut off messages on the display, i was scared shitless! but i unpluged the battery and plugged it back in and everythin was fine...
