You have to open your ecu and see which one your sled has. The top right hand side of the chip will have a black square,circle, or triangle on it. Order a chip puller or you'll wish you never attempted it cause once bend a prong it will never line up. I've done this a few times and it's pretty easy with the puller, and yes they snap in place. Pretty good gains but not sure if i would spend the money again, clutch kits seem to work better than the chip for your money. Does smoke less which is a plus. Reverse kits from cat are around $600 ,not cheap and if your not much of a mechanic don't attempt. good luck hope this helps.
Do you think the chip that you have to buy for twin pipes is also the one that they sell seperatly? I was wondering because I would get the chip first and then latter on get the pipes. So do you think it would run normal with it and still get good performance and not have to get a different one for the pipes?
