What type of FI are you running? Where are you injecting the meth? Could slow you down with too much, if it is coming on too soon, or if you are not tuned optimally for the meth.

I drove out to the cottage with the meth powered up. About 90 miles. The little 2 qt tank that comes with the Snow kits just won't cut it for daily use. I don't have a switch yet but I can pop the hood and pull the fuse that I wired into the system.

I am running a Magna Charger, Have the meth injecting right before the T.B., Have the meth comming on with rpms, I can change how much I run from the inside of the truck, Running about 9 lbs of boost

Default Temps with meth...

Ok guys, the meth doesn't really help your air charge temps, for that you need to do something with the intercooler's efficiency. The meth lowers your combustion chamber temps during the process and that is what allows for more boost and timing to be used. If the kit is not tuned when installed than yes you could run into tuning issues. You really should use the 50/50 mix to get the most out of the kit. The water is a big factor in the cooling of the chamber.

Well I heard that so I changed to a 50/50 mix, Water and alky just to make sure and my truck run like sh*t so I told the guy I got the kit off and he said who in the world told you to put water in it, Run it out and remember 100% alky NO WATER, What I wanted was to lower my combustion chamber temps so I could run more timing and have higher octane, Haven't upped my boost yet but at the same high timing turn the alky on the et drops but it does help me with the traction problem

to get around the 2 qt problem i am using the factory bottle ... it holds 5 qts!...and tells me in the DIC when it is low.
