I do have a controller. The AlkyControl kits have a gain **** that controls the ramp rate of the progressive meth controller. But if I turn it down where less sprays, the pump can't create enough pressure behind the nozzle to atomize the meth. There's some setting on the pump that I should be able to adjust though...I'll have to give Julio a call.

Jack the **** up, break the **** off, make sure the tank is full, go tuning.

I don't care who you are, if you get a tune dialed perfect with it turned off and then expect to turn it on to see benefits, your mistaken.

With mine turned up to max I always shot for afrs in the 11.4 range with 20* of timing. I did this on both 14 psi and 23 psi with no problems.

10#'s 9.5:1 I'd tune aggressively at 11.4-11.6 @17*-19*
10#'s 9.5:1 I'd tune moderately at 11.2-11.4 @ 16*-18*
Give me some 110 mix, I'll hit 22*-24* without blinking my eye.

Being a turbo you will want to work up to that. I'd tune by your boost/power curve.

It's funny though, like trever1t says, his may act like a dog at some of those numbers. It just all depends.


That's no science, that's just me being comfortable and getting a feel over the years of being around here and listening to horror stories. Feel meaning I notice more stories of blown(dead) motors on anything above 8#'s of boost and 11.8:1 for in the 9.5:1 ratio. Will your motor blow there? No. But I am not comfortable with it over time. On the street, running 17*, I am not scared of 11.7-11.8. But as soon as I cross that psychological threshold of 9#'s and 18* of timing at 9.5:1 I start changing my comfort zone.

These numbers I discuss are on my wideband. Again, meth's stoich is different, so anyone could argue I am going about it all wrong. Which is fine. Measure away.

BTW, turn down your meth to get you into the 11's. You are just spraying too much.
