help modding plz

thats what i wanted to do its actually kelly blue booked around 4500 last time i checked, but i havent finished paying it off yet one more year plus my parents are ticked that i want a faster car:spank: i tried this morning with a camaro in the classafieds but no luck yet. so in the meantime i was going to make with wat i had, ive looked at all the options trust me its just best to mod it a little.
As for the venom 400, if anybody has one plz post how it works, from what the company claims it shifts the automatic faster. ie>not a two sec. delay. i think you guys are right on with the whole tricking the computer thing although they claim to increase hp. can anybody conform, this was one of the things that i was going to buy.

Thanks,
Shane
