FYI I’m running a cat-less downpipe, 91, and 2 gallons of e85. I disconnected the meth for now and will add it later on but so far I really don’t miss it.

I would also like to mention that forum member “chenry”’s car has the same flash and is stock except for a drop in air filter.... his car is like a rocket ship as well. We had the tunes done at the same time today and both left with huge smiles on our faces.
Could you just run the meth in addition to the tune and have the benefit of a higher octane when going full throttle?
