Im dont think it matters how much boost. Meth cools the temps down for more performance.

you can max out the stock one without meth

yes but with meth we can hold the power longer with the turbo and most ppl do fine around 10% more HP TQ. and yes you can up the boost a few

You can run 24+ psi and the meth will help gain efficiency back plus add octane. It's worth the money IMO.

I'm running 25psi right now on meth. I'm in the middle of data logging for vince right now

I did get a P2187 code the other day...I don't know if that has something to do with meth

i believe thats a rich code caused by the extra fuel from the methanol

If your running rich that is bad at least from what I know anyway. Maybe try putting a smaller nozzle on until you can get the retune.

your fine just let vince fine tune it. term is still getting mine dialed in.


im runing a 5gph nozzel on mine.


i have a progressive controller and mine starts to kick in a 6psi and pumps 100% at 15psi. it says in the manual to have it start at 25% boost and then full blast at 75% boost.

I'm at 23.5 with full bolt ons and trifecta tune and vince wouldn't allow me to go above 23.5 psi because the turbo was @ 100% efficency. I'm now going byt/tf tune with meth and hoping I can put the boost up a little more with the meth. With meth gaining back turbo efficency will that allow more boost I couldn't get w/o meth?

Correct. It helps aid in the efficiency department.
