Have any of you guys put one of these on your car? is it just junk or do they work?

thanks!

 

From what I've learned in the little bit of research nice done is you need to use an obd1 ecu and have it "chipped" (just means it can be chipped they put a pin slot for you to use one) most chips you're going to find online are generic base maps, you would either want a reburnable chip or go get one made for your specific set up

Hope this helped, not sure how credible I am on your topic yet.

on a stock automatic ls.....no save your money, sure they work as a crutch to get tide your car over till you get it tuned but that's all they're really good for.

 

If your talking about the resistor that fools your IAT and floods the engine with fuel, its not worth it.

 

if you have to ask this question, no It wont help, if you don't know if you need a tune or no then you prbly don't have the mods that make a tune nessesary

 

plenty of better thing's to spend money on

i heard neon's are all the rage
