That Gti couldn't keep up (as long as i was spooled up) very well.
No one recommended it I just thought it needed it with 170k on the original maf sensor.
Next mod... I would really like to go big on a turbo, but funds are low and I have 4 vehicles. My 84 Toyota needs some love. But I do want gauges and a new custom downpipe and maybe some balanced pp520's.
Just got to Phoenix and
my average mpg hand calculated was 55.85!
so far I am
happy with the setup. Also had winds of 10-20 mph, rain, 2 sandstorms(errr, just got my car painted for this reason!), mountain climb up to 4200 feet , AC was on 20%, and cruised control at 70! Wife would not let me do 65
so I think with the current setup, good road conditions, and with out the extra 350lbs in the trunk(dogg, cage, case of coronas, tools ect)
60 mpg is achievable!
