3 more degrees should make 715-720 or so

with timing watch your torque

Do you guys think boost is where its suppose to be the pullies should make 18.5 19 psi I didnt think I'd loose 4 to 5 pounds with cams and long tubes ,anyway getting some back in the tune .

What should I be looking at.
-
boost is a measure of restriction, larger cams/overlap and a free flowing exhaust will drop your boost.
want to change your desired boost, pulley up!

If you want to run this boost level, I'd say more timing, I run straight 93 octane on mine, 26psi, 22 degrees, but 8.4:1 compression.

So little more timing will net little more boost.

Yes I've looked at pullies but I can only get 2.7 so 2 more pounds off boost I'm told i knew I'd loose some boost threw cams but not quite this much .

Less boost means your engine is moving more air. Thats good! Timing does not effect boost.Boost is a measurement of restriction
