It still doesnt look free

 

thats casue the only thing free gets you is junk

 

 

ok 1 cats, they dont add much hp if you take them out, but it helps. cut them off. 2 not my idea "change the thermostat to the lowest temp you can get. 160 degree if you can get it, if not then 185 might be the lowest for it. Right now it will have a 195 in it. It makes the computer think its cold so it richens the fuel/air mixture and gives hp.", 3 take out the air resticter in your intake. 4 there a a rubber peice that goes into your fenderwall from the air filter box, remove it. Theres some easy, free things. also next time you change your oil, use synthetic oils, it gave me 9 hp(but a v8), it should help u out, and be better for your engine. Get some fuel injector cleaner, especially with 90xxx miles on it, it will help. check if u need new plugs/wires thats helps alot if bad. then last maybe get your hands on some HIGH octane racing fuel to clean out your system. Hope that helps ya out.

P.S. get some CARB CLEANER, buildup can take away up to 15horses!!!

 

ive said this before and i will say it again, do NOT touch the silencer, over 130 mile trip i got about 15 mpg with out it, i get around 20 normally

 

thanks for the post about the silencer and not to do it because I was seriously considering it, but what about that rubber peice that guy was talking about going into the fenderwall?

 

its not hard to take out and put back in, as long as you dont cut it, try it for yourself, but over aboot 130 miles my milage went down a bit, and no it was not from leadititus

 

ok, so your saying that if i get a k&n on a stock car(wich gets more air flow) i will get worse gas milage???
