i have a 99 f350 with 9in lift 6in stacks programmer gauges ect. the friend of mine that i bought the truck off of gave me a brandnew wicked wheel, aftermarket blow off valve and what i think he told me was an oil pressure valve. my question is should i install the wicked wheel and the blow off valve or not. i do some heavy pulling in the summer but very few other then that i just pull my boat. will the ww and the blow off valve give me better performance or is it just nt worth it in my situation? if i should how hard is the install on the ww and the blow off valve?
Not sure what the blow off valve would be. Probably not necessary on our 7.3s. If you're referring to some sort of MAP sensor fooler, that would come in handy.
The wicked wheel helps if you experience turbo surge when towing or cruising up a long hill with heavy throttle but fairly lowish RPMs. It's not too difficult of an install... there are several threads detailing the installation. The Common Mods thread that is stickied up top is a great place to start.
