Re: make it fast
As far as the gxp. I would save up about 8 wks before you get started modding, the gxp is extremely limited as far as mods. I believe they now make a cai/hai/fwi, headers. The gxp is not the best car as far as mods. enjoy what you have...

DDM tuning HID 6000k hi/lows and fogz
FWI, 180*tstate / 18 inch enkie wraped with potenza run flats , danturs tuned pcm,
Home made motor mount / autolite 605plugs/beldin performance wires. Hogan 3 inch dp w/ magnaflow hiflo cat, zzp plot and 3.4 smoothflow MpS, trans go shift kit, 10 inch gtablet mounted running torque app.
I have a kr issue please help....

Re: make it fast
400 WHP isn't gonna happen with anything short of a turbo, which is going to involve a ton of custom work, money, and someone who can tune it. They don't make headers for the LD8 in the Bonne, and no one makes a CAI that fits the Bonne, you get to custom fab.
If you want to mod, you picked the wrong car.
Check ebay for the parts you need, and possibly start another thread, in the proper section.
