Best gain for $1500?

[oleshifty]

10-15 was dyno'd on stock 6.0 gto...i'm assuming closer to 10 on stock truck...closer to 15 on mod'd one.


As far as the system thing goes... i upgraded to a 145amp alt, and ran better cables, and my lights still get DIM at stop lights with stereo going...but are 100% normal once i start driving. Worth it IMO...and according to the ass-dyno. Was NEVER able to spin the 35's until i put it on, now i can squeal em from a dead stop.

I have never seen a real dyno graph showing more than 9 rwhp with just the addition of the underdrive pulley. That doesn't mean no one has, but I have yet to see one, and I've been looking for 5 years.

As far as the topic at hand, how come no one has said nitrous? Biggest gain for the money hands down. Still like said I would upgrade to a 6.0 first.
