How's the smoke?? I had one of my guys follow me at night while I rolled the throttle on, and under full boost I had no smoke!! (SW#7) I then slowed down to let him catch up...(slowed WAY down
) and then gave it half throttle and accelerated that way, and still no smoke.. I'm one of those guys who doesn't like smoke...I know...weird.
On SW#9, it looks like there is a slight gray haze in my rear-view mirror, but I can't pay attention too long at what's behind me..everything in front of me catches up too quickly!!!
Boost is very responsive, my last 500 miles is with the twins and my mpg (hand calc. of course) was 15.64. There was a lot of full throttle miles in there too! I fully expect that if I drive normally, that I would get 16.5 in my normal, in-town driving, which is pretty much what I got before twins.
My mechanical boost gauge reads 44psi measured at boost bolt from intake. I can hit 46 on SW#9, but will probably go back to SW#7 or back off SW#9 pod a little.
Also, Keep in mind that I still have my catalytic converter in place, and plan on keeping it in place too.
