No Its a computer controled Fuel system! Ive heard about guys putin a performance chip in them! That mite get u 10 to 20 horse! A camshaft is a sure bet to get 35 to 50 horse! If u want to spend sum cash check into a Vortec Supercharger! That would b sweet!

A cam would be the best bang for your buck. Also, I would put thinner head gaskets on it to gain compression for power and gas mileage. That year model had low compression. You might be able to put aluminum heads, Edelbrock has some nice heads w big valves,on it so you don`t detonate and get around 10:1 compression ratio.

If you go change the cam and/or heads, you are probably looking at a custom tuned CPU. I hate to bust your bubble, but in all honestly, without spending some major cash, your gonna have trouble getting around your buddies turned up cummins. With a flick of a switch they can add over 100 hp and flick the switch back for stock programming and the only way you can compete with that is RPM/horsepower and to get it you need a major overhaul of the motor. Even with a supercharger, you need to revamp the entire package to handle the 'charger.

You can still run factory CPU , just put a chip on it. We did it to a 90 model, just don`t go to radical on cam. Off idle to 5800 rpm`s and you should be fine.

There you go. Problem is if he want's to beat a juiced cummins, he'll need more than 5800 and a mild cam

Farmboy94........If yer buddies diesel is juiced up to any degree at all, you've got your work cut out for you. Not saying it can't be done, but, to get a gasser to that level may render it unusable for towing, cruising, etc..........

You`d have to have a light vehicle to get the job done. Don`t try to out pull them,they`d have a gob of torque.
