Got the 1st heat cycle on the Camaro engine this morning. I must have done something right with the new Terminator X EFI install & tune.

I was alarmed with the lean AFR reading around 25.00, I think I figured it out. I didn't have the mufflers on & that caused a false lean reading with the O2 sensor. Holley wants 18" - 22" of exhaust after the O2, I only have about 6" with no mufflers.

Back out to the shop to fix the issue & put another heat cycle on the engine.
