Like I said, the bolt-ons and Diablo will get you up to 40HP and if you get a tune with that from Diablew you might see up to 60HP.
    Ahh i see, so i should expect about 350 hp at the wheels? And i checked in the glove box and saw a string of like 5 numbers on a white sticker, would that be the rpo?

    Yes......Those series of letter's & Number's are your RPO codes......Along with your Trucks Vin#.....Go to the below Site & Enter your Trucks Vin and it will show you what your Truck Came with from the Factory....Engine,Trans,Rear Gears and so on.....

    Yes, but before you buy anything make sure the gears you pic will fit on the stock carrier. You can one for $489.00 from summit racing, And you can get one for $513.00 from 4 wheel parts.com

    ahh, well would it be simple enough to install? or would i have to take it to a shop? I know the other things i have chosen are relatively easy.

    Well its not that easy and you need some special tools, not to mention that when you swap gear sets you have to get the contact pattern just right, If you dont the rear end wont last that long, so you would prolly want to take it to a shop, Good luck.
