Whats up guys. Just traded in my 08 cammed silverado for an 07 grand prix gxp, I am very pleased with it so far. Just did a 16 hour full paint correction on it see pictures. I am heavily involved with performance so suggestions are welcome. Thanks for having me.

Sup.

Read the LS4 section on Ls1 tech for info on mods if you plan to do them.

Intake swaps and turbo's are pretty much your only options, along with a downpipe and small things. But if you plan for power, build the trans, it wont handle much past the 250-260 crank HP the car puts out.
 
alright i will. im trying to get ahold of black bear performance since i had my truck tuned through them to see if they can tune this car. is there a lot of difference with a tune on these cars?

With everything stock, you wont gain much at all. Might get a few more HP with being able to adjust the MAF and see how much KR the motor is getting and make small changes from there. But if the car could breath more (exhaust) if would just be all around better and a tune there can be more helpful. Anything after the cat will gain zero HP, just some FYI. Still alot of small things can be changed like fan settings and such.
 


going to the track on the 21st. what kind of times should i be expecting? with and without tune. Also seems to act like it has a looser aftermarket converter kind of like the 3200 stall i put in my truck sept this one brake stalls to 3800 rpms
 


as much as i want to do a turbo this thing will wheel spin like crazy seems kind of pointless plus since ive only seen remote turbos i dont want to be running that in the winter.

There is a car tuning turbo kit, but its overpriced. $5000 is a lot, especially when you factor in the nice expensive transmission to go with it.

Rear/remote mounts are inefficient, that "cooling" they advertise because of the long distance between the head and the turbo actually causes it to spool very slowly.
 
alright thanks guys ill keep looking. Jeez i hope i dont run 14.5 in the 1/4 this seems a little quicker than my old truck but not by much mostly low end. my truck ran 14.6-14-8's.
