They have done everthing to fix the missing pieces, wrong pieces, etc but first dyno we could only pull 390.37hp with 340.77lbs torque. Hell at 5psi it was only 322.22hp with 273.65 torque. Oh did I mention they sent the wrong sprayers for the methanol injection and sent a 2 gallon jug. Now where in the hell is a 2 gallon jug gonna go in a 370?? Next Monday it's going back in again. Project started in June....

I don't think i'm gonna go with their kit though and I was thinking of building a custom tank in the trunk because as you mentioned there just isn't much room in our car for any of the pre-made tanks. I had recieved a dyno chart from sts with higher initial numbers but then i added a resonator it seems to have dropped the numbers a bit. Are you running a resonator on your setup? And do you have hfc's or test pipes? I hope you get your problems resolved quickly, I am curious as to whether you feel the methanol injection is worth it.

"A combination of our patented remote-mount technology combined with an intercooler provides the lowest consistent air intake temperatures over any other forced induction system on the market. Owners of otherwise stock vehicles will experience 470whp @ 7 pounds of boost, but also receive the benefit of increased fuel economy over the competition. The beautifully tuned exhaust note from an STS Remote-Mount Turbo System is sure to put a grin on your face as you flyby all those other imports."

Was told they talked to the guys with STS and they said there should be no problems hitting the 450-470 range, but yet again I'm the guinea pig. They have never installed a methanol injection system on a 370z. I was told the spayers they sent were for a V-8 so they sent a pair since it needs to hit both side of the engine. I'm hoping that by tuesday I will have the final numbers. So far $11,000 for 92hp...damn I got screwed
