trade up to a ford
vehicles arent really cheap to mod. i think best bang for the buck is thoes programmers or chip it. maybe a K&N even though i disagree with them. if it lets mor air in it has to let more dirt in, so i wouldnt run a k&n. other than that i would say a free flowing exhaust, chip it, maybe go craazy and super charge it i think chipping would be the best thing to do though. i would wait until you get out of base warrenty to do any thing because, and i dont know about chevy, but i work at a ford dealer in service, and if we find any of that shit on the we wont warrenty any engine, or trans work to be done on it.so you would be screwed there. but like i said you could spen 1000 and not really gain anything. also another thing to look out for is people that tell you the tornadoes and shit like that are great for your money. to tell you the truth the horse power gain is only in there head to really gain anything you need to change stuff like a free flowing exhaust, bigger intake, different cam different heads that is where the power is at, not just doing something like a k&n. but for what you want to do you might want to look into chiping it, i have seen a noticable difference personaly with that stuff. i have tried a bunch of the other stuff, and you really dont get a gain out of it. just my 2 cents oh i reread it to make it look better. sorry get new wheels i think thoes change the apperance the most
