DHP tuner work on 04+?

[OH4CompG]

Hey guys, just curious if any of you know that a DHP tuner will work on an 04+ GTP?

[Sabrewings]

Yes.

[carlover89]

just the 04, 05. or thru the full range 04-08?

only the 04-05 pcm are tune-able.

So if you owned a 06+, you'd have to swap to a 04-05 pcm. Your gas gauge will read backwards. There is other info that goes along with it too, but thats up to the person to figure out.

pull the radio and onstar fuse before flashing.

That's only on 07s I believe. I don't think the 06 had the gauge issue. Overkill has fixed the gauge issue if you get his PCM.
