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.

like bad boost as in false boost..aka like boost stacking

that makes no sense at all. There is no such thing as false boost, boost stacking is just a bad term for not flowing well.

No one has answered this question yet. Any knowledge on this subject?

do tr6s or tr5s i forget

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.

I thought i typed it must have deleted it. Maybe a degree or so. Nothing major.

Ok, thanks guys!

Both! :th_laugh-lol2:

I was gonna say... LT1's were 350 SBC's with a few changes from the gen I

sorry! i meant LT1 or LS1 my fault

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!

94 couldn't be LS1 unless it was aftermarket.

LS1 came in corvettes in 97 and F-bodies in 98.

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

Always one year earlier with the damn Y body then the F bodies...

i was basically asking if he did a swap... i got a buddy with a LT1 cam and he put a super charger on it.... 11 sec car
