I have a 2004 GTP, and I'm also on mnclubgp and alot of the tuners on there won't touch my pcm because they say 04+ pcms are weak. I have some mods such as headers, colder plugs, msd wires, zzp 1.0 pcm and I just ordered 1.9 rockers-so I dont have these installed yet. Just wondering what kind of advice do you guys have that I could do for a GOOD tune. Also thinking about dropping to a 3.5 or 3.4 pulley soon as well.

Read, learn, buy HPtuners and tune your own

Your local tuners sound dumb. The only one who has figured out 06+ is overkill and he ins't sharing his secrets.
Get HPTuners and do it yourself.

Thats the problem I dont have the time/money for hptuners. Full time student and work. Also dont have that much money to drop on a tuner.

If you can't afford a tuner, you shouldn't be modding bro.

I'd bet that's because they're using DHP tuners and they don't have 04+ tuning capability. 04+ is very tuneable, you just have to know what you're doing (like most things right?).

i think some of the DHP's were 04 capable werent they? i thought the last hardware version was made for them. i know my hardware wont do it though :-(

Not sure what Charles unlocked in the software for everyone towards the end. I know he went and unlocked 98-03 for everyone but I don't believe the average DHP PT has 04 or 05 support unless it was paid for. I've got a commercial DHP license so everything's unlocked.

I only know of one DHP in the pacific nw that could touch my 04 gtp and it is owned by a friend in Seattle that purchased it from Mike Lewis of PFYC.com
I have hpt now though

I'm able to write to 04/05's with my PT. Cleaned a couple of codes off and written is about all I've tried though. Typically I use the HPT.

any DHP works with 04/05, i use it often.
05 drives me nuts because there is no partial write support... I refuse to do overly custom work on an 05.... the crazy 04 I am doing is bad enough.

Ya seems like quite the headache for me.. Im pretty busy with work and school already let alone dinking around with one of those. Thanks for the help tho guys

umm... the guy who helped you above, overkill will set you up with a good tune. contact him, his **** is cheap for what it entails.
