Recently we showed you how easy it was to tinker with the late-model LS1 and make power by simply installing a throttle-body, a larger mass air meter, and using Hypertech's Power Programmer III. In the end, we were pleasantly rewarded with 325 hp and 334 lb-ft of torque to the rear wheels.

This tiem, we latched onto a '99 Camaro Z28 with similar mods, but opted to install an underdrive pulley to reduce the amount of power required to drive the accessories. We also tried all the tricks that the F-body guys have developed. This included a homemade ram-air system, an EGR mod, and the throttle-body bypass. The final dyno tally on Morgan Motorsports' chassis dyno revealed results as impressive as last month's considering that the Z28 didn't have the benefit of the larger exhaust and factory ram air of the SS, and we surpassed the power numbers produced by a stock SS. So read on to find out how you can gain more power over the weekend with a few simple tricks!
