Default Jeff, when are you up for a CA emissions test.?

I'm thinking of Hartman or New Dimensions installing a stage 3 in a few months and would like to see how emissions testing with it goes.

Default Keep an eye on it Jeff. My 110 started out just as you mentioned, it then started to

"moan" (really) and then started loosing boost.

I ended up putting the hyperboost valve back in. It's not a smooth as the 110 was, however I have my boost back!

Ah well yes, you do have to "adjust" the ECU to take advantage of higher octane gas
