I have a 05 Bonnie gxp, is there any performance mods out there?????

Please start a new thread rather than adding to an existing one. I have moved this into its own thread so that you can get better visibility.

The 05 GXP has a locked PCM, so you can't tune for performance.

There are very little engine performance mods out there. GXP Venom has added NOS to his, and he would be the one to talk to about what you can and can't do with your ride.

AEM EMS Stand alone engine management, that step alone is over $1000 and involves rewiring the entire engine. You would also need a transmission computer to go with the EMS, so another $500. Then go from there. This will give you full control over the engine and allow you to make any modifications that you want, but there isn't much of an after market and you would have to fab most anything you wanted to add.

Weren't all the OBDII PCM'* locked at one time? I also have an '05 GXP and would really like to get an upgraded PCM.

Why has no one unlocked this specific unit. Is there something odd about it?

GXP Venom would be the guy to talk to he has done mods to his and last i heard doing anything like a PCM will be over $1000 just for one that can be messed with kind of a hard pill to swallow just on price tags

For tuning you might check with this guy or one of the other few -seems N* PCM tuning has become reality over the past few years.
Could really make things interesting... like swapping over to STS heads and PCM .... tuned for 400 HP.

I've tried, but that stupid website will not allow me to send a message until I've made a certain number of posts!!

I did get an e-mail from Wester'* Garage saying they expect to have programming available for the '05 GXP with-in weeks.....but it'* $495!!!!

im in for one FOR SURE!



id love to have my bonnie tuned!

I'm not surprised at the price at all, since they'll be the first to do it.
