looking for something free. crome,uberdata ect. I dont know which one has nitrous features . plus if i d/l one of these..is it hard to find someone who knows how to tune with that software?

my 2nd question is can one of these rom editors retartd stock timming? or do I have to buy one?

an 3rd when running the nitrous options on a rom editor how does the ecu know your spraying? when im at WOT the nitrous would kick it...thats if I have it armed up or not.

thats it. thanks

 

anyone?

 

why dont you go download them and try them out?
