I got to the stg1 supercharged and stg1 twin turbocharged shop-monster back to back around the block and WoW!!! Be warned, you will hate your stock car.......

Both cars are very tidy under the hood with a seamless integration of electronics, they could have come from Nissan that way, both idle well, quiet, tame and civilized in traffic.... The S-charged car delivers the power in a very linear fashion resembling the stock power curve but higher and significantly better up top.... a lot more power on demand. This bolt-on setup is very livable for daily use and a ton of controlled fun, as if you dropped a V8 in the Z, a serious transformation guaranteed to keep you grinning
The Turbo is a hooligan, especially in the low gears, the VDC will completely cut you off at WOT and if you turn it off without the GTM-tuned traction control system, you better know what you're doing!!! Guaranteed to satisfy any mad power craving if the supercharged doesn't do it, either way, you would have to relearn how to drive your car... the character and limitations change.

I'm gonna hold off on discussing my plans for the Z until they become a reality, thanks GTM
