Need? No. But it would help. Even on a completely stock car, a good tune, a little bit of spark advance, stuff like that, can help out and get an extra few horses. Adding pulleys, CAI, Exhaust, and an intake spacer would change the engine geometry enough that a good tune would gain some significant power, like maybe 10hp. Maybe more if you got someone really good.97v6Silver said:dpes he really need a chip with out a serious power adder.... i don't think so, ide say go with a body kit... i know it's not preformance but that stuff may not cost $500 but it will cost at least $500 or more to get it installed...
With ALL the bolt-ons I mentioned above, you stand a chance of beating a stock 98 or older GT. If you're a good driver, and particularly if you get some high-ratio gears. You won't be beating any 99+ GTs any time soon, though. You need a cam + more to bump you up into that range.Wickky said:man i love the way my car looks now i just wanna beat some damn GT's
They'd be best off the line, but watch out if you do any highway driving...Wickky said:4.10?
Well you can calculate it. Stock axle ratio is 3.27:1. So with 4.10s, you'd always be revving 4.10/3.27 = 25% faster than you are now.Wickky said:i heard it only raises ur rpm's by like 300
