Here's a few more items to go along with the update. I got the MODO Innovations pedal mounted to the LS7 throttle by wire assembly.
I also got a Nitrous Express LS7 MAF system. It's absolutely trick, it ties into the TPS wire on the engine harness and self learns where WOT is, which in turn is the switch to activate the shot. The nozzles and solenoids are all contained in a billet MAF housing that's annodized black. It's a beautiful piece.
