Do you mean bad boost as in higher or lower?

My car has a 3.4 and I only run a peak of 7.5 lbs. I know my car needs a tune, but I was wondering if getting a tune will make the boost go up. That would not make sense to me being that it is a belt driven supercharger and boost goes up with rpm. Just thought I would throw it out there and ask since some of you have been so helpful with the other stuff.

having a restrictive engine = more boost

so in his case, not having the proper exhaust mods.

correct...since he dont got headers..u bend delete blah lah..his stock stuff is restricting ..there in turn showing he has moore boost...when really its slower then stock
 


colder temperature plugs will help a little, not much.

tr6's, tr5's are stock or apparently one range cooler, not sure i trust that one though.
 


The only thing that sucks is that the GTP is faster! Oh well, the formula is still more fun to rip through the gears in, and at least it is RWD. That's the best part!
 


lol i raced a old school formula and it had red/orange #%) lettering on the fender i think..he flicked me off after i smoked him
