i actually have one of julio's kits still for sale that i had on my s/c'd LT1. i really liked it once i figured out why i sucked at gravity

i like his system cause you get alot of control with it, such as what pressure to kick on, how much flow you will have at initial hit and the ramp rate for how much it adds as your boost grows. i also never went through a whole lot of it which was nice, cause meth was like 3.00 a gallon and would last over a month. helped me tremendously being as it was not intercooled and i would normally see IAT's in the 170-190 range going through the traps, whereas with the kit i was at 80-100* IATs during summer months, and at one time it was about 60 or so out, and measured IAT's as low as 40*. also some people would say use nitrous, but the reason nitrous makes so much power is the fact itll burn hotter in the cylinder and it actually promotes detonation but provides a cooler intake charge. with meth, you get the cooler intake charge but add fuel instead of oxygen and as a result, not chance of it causing detonation.
