Your GOAT will thank you. Your neighbor with the

Mustang will not.

In case 400hp is not enough.  An 05 or 06 GTO can make 600hp on pump gas with an HO intercooled system.  This system uses a P-1SC-1 at 6 psi and an intercooler designed just for the GTO.  This same system for an 04 GTO is set at 7 psi and you can expect a horsepower increase of 50-55%.  The GTO systems and kits all use an additional 8 rib drive system.  For polished head unit add $250. 

These systems and kits come with a 12 month warranty and the HO system has an optional 3 year warranty for $49.    The HO systems are 50 state legal (EO D-365-6).

A tuner kit, which excludes the fuel injectors, fuel system and computer tuning, is also available, and is otherwise identical to the HO Intercooled system. Upgrade to a D-1SC head unit on this kit for $230.  A race kit is also available with an F-1A head unit for even more boost.
