Methanol Injection

has anyone installed a water or Methanol Injection Kit yet, and what are the power gains you guys are getting....or should this be one of the last mods I do?

We installed one right away on the Red Shed as we turned the boost up. Our water injection yields the same results on pump 93 as 100 octane.

with the kit you sell on your site darrell?

.....yes sir.

does your system use a progressive injection style or do you just set what psi you want it to kick in at? also alot of places claim 10 to 15% increase in hp with 100%water...is this what you have found or are those numbers exagerated.
