The HPF are also doing their fair share of big horsepower, boosted LS1 upgrades using the EFILive 2/3 bar operating systems. HPF have developed their own Twin Turbo kit for the LS1, which is a nice way to run 9’s if you wish.

LS1 tuning guru at HPF Martin Rogerson is lucky enough to drive to work everyday in the HPF Twin Turbo LS1 which just happens to run a 9.83 @ 141 mph with factory bottom end, turbo 400 transmission and the factory IRS.

Here HPF are proving you don’t need to look to an aftermarket computer for running big horsepower LS1’s if you are running EFILive’s 2/3 bar operating systems.
