I have mixed highway and city and drive the car 5 days a week to work 62miles a day, I average 18mpg with a good amount of accelerating.

RE: tune update VMP
I'm running the "8 psi" (on the gen 2's it might be more) right now. Justin at VMP got me to pull timing 2000-4000 RPM by -4 degrees, and the knock stopped. has me worried, because it was knocking really bad before. Hopefully no engine damage (sounds fine now, even after some hard test runs). thankfully the knock was at such low RPM.......the added load of high piston speeds would have snapped a con rod for sure!!
Anyways, I'll be getting it dyno tuned next week hopefully, and also passing the datalog / dyno info Justin. can't hurt to have two opinions.

RE: tune update VMP
I am going to get a VMP dyno tune eventually, dont think I trust a mail order tune for any FI.
Just need to get the equipment so I can start to hoop up the power I have now, before I go for more.
