I couldn't tell you due to the fact I don't run the stinky stuff I transport in my van and It is to smelly even the engine smells bad. I did how ever have to richen it up from initial settings I am putting a tunnel and pipe on it, using a mac header and a mac quiet pipe the guys think it was a little noisy stock with the restrictors and I am looking for more authority when pulling out of a hover. But technically speaking a guy could run a couple or degrees of advance on the timing with out a detonation problem, which would give more mid and top end power. but before I did that I would check with Todd.
