No. The HPFP just can't keep up with cap on the DME. You need meth to make more power. I run usual straight meth VP M1, klean strip green denatured alky (90% ethanol-10% methanol), or ignite e98 (hard to get). Any e in the gas tank my I won't hit targets or I end up hitting th fuel cap.

You have a meth kit tho right you're not just mixing it in the fuel tank?

Yeah I don't mix any e in the actual gas tank. On straight meth on the most aggressive setting I'm holding 21-22 psi till 7k

Timing also really starts to ramp up when meth is flowing.

Obviously I don't always run it that aggressive
