Just got my car back from Texas Speed and Performance in Wolfforth Texas and I now have 90 more horsepower .Mods were RKS headers, LS-6 intake manifold, Stage II 5.3 litre LS-1 heads package(Patriot Performance), 228/ 228 Comp Cam, new plugs, wires and 180 deg thermostat. I am currently using the K+N FIPK and Borla stinger quad exhaust.The 2000 6 speed dynoed at 310 BHP at pre mod and over 400 BHP ( at the wheel) after all was done with LS-1 edit and the dyno.I kept the stock cats in line....The guys at Texas Speed did me well- they are really great...
