Thread: 1st time potiac, long time gm....

Well the opportunity came to purchase a beauty 04 GTP, so I jumped all over it. The previous owner installed a stellar stereo as well as a Borla catback system. I have owned it now for a week and lOVE the throttle response above 100km/hr (60mph). Awesome interior, love the leather bolstered seats.

I look forward to adding some more power and some serious style to this already wicked faaassssst car!

Welcome!

"this isn't my first rodeo...." I have had many mod cars, just been in the 4x4 game for about 5 years now. With this car I am looking to get back into the sports car arena. Having a best bud with a s/c 300 (550hp) and my step-father with a s/c 427 IROC (800hp) I have alot of knowledge to call on.

With that said I will be looking to only get down to a 3.4/3.5 pulley with most the parts to go along with it. Of course the pulley being the last part to bolt on.

I could see within my first highway drive and without reading the forums that this car needs a cpu tune. Definatly a flat spot mid rpm and shift points should be a bit higher.

I can see this is an excellent forum with some very good info, thanks to all the contributors!

Welcome sir let the grand prix modding begin

welcome.
