Ok i installed the manual boost controller, and gauge. I have the boost turned up to like 11 or 12. Its so cold outside that if i go higher it hits fuel cutoff to easy if i full throttle.

Anyways, its not bad, i think i was expecting more but still quick. What are your mpg running a boost controller?

Kind of like a poll here, what mpg you get at what boost set. Highway or city driving?

I was getting around 20mpg with stock boost kind of mixture of driving, never more than 5-10 min on highway though. After turning the boost up, i am getting like 19.3. What is everyones average and whats a good way to get the mpg back up? Obviously turning the boost all the way down might do it. ECU programming help?

 

Turn up the boost the correct way...with a tune.

Chances are you won't get the mpg you did before with upped boost. More air = more fuel.
