Holy Batcrap Josh... how the freak did you get 370 miles out of a tank?! Did you pay attention to the MPG increase for each of the mods? I have done LOOOOONG, SLOOOOOW highway drives (average 70mph) and have NEVER gotten close to 370 miles on a tank... and I run mine down to at least a 20 gallone fill-up. I'd like to know what I need to do. Anyway... I'll continue to drive and enjoy the VX no matter how bad it gets...
It's not a fluke... I've repeated it three times now. I can get 370 miles per 22 gallon fill up now with my mods. Prior to that, I was happy to get 300 per tank.

I think the PV cat-back system was the big boost. My Calmini Filter gave me maybe a few more miles, and I can't see how the Interceptor would give me a whole lot in milage. So that leaves the PV cat-back as the biggest gainer in MPG.

16.8 MPG seems to be my average now, with my mix of highway/in town driving. I suspect I could push it to about 450 per tank straight highway. Next time I go to Colorado, I will try to run it to empty and see how far I can get on a tank.

BTW - if I have the AC on, it will bring my full tank run down to about 330 miles per tank.

As for how I get 22.3 gallons in my tank, I fill that sucker up to the brim. Literally... The tank is filled all the way up to the top of the pipe into the tank. It takes a little while and finesse to get the gas to go in after the first couple auto-shut offs, but I've wittled it down to a science

By god, there will be no build up of gunk in MY tank!!

And Randy!! Where's my tires man! I've been waitin' for your call
