Doing some Mods need Guidance
Hello Long time reader first time Poster lol.
Anyway, I just ordered some goodies the other day for my 2001 F-250 SD. It has 52,000 miles on a 5.4L 4X4. I ordered the Hypertech programmer, Crane quickflow TB spacer , a BBK 75mm Throttle body, underdrive pullies, a catback exhaust system, and Im looking to replace the K&N stock filter replacement with the whole Cool air system from somebody. Parts will be in tomorrow except exhaust. What im thinking of next is injectors. What it the stock rating and what can you or would you go up to? Any other suggestions without total disasemble? I guess a cam change on these would be pretty easy. any suggestions. Thx guys

Well, the cam change is time consuming since you have to do both heads and the whole front of the engine has to be disassembled to remove the timing chains. Cams are kinda pricey for these engines too since it requires 2 and almost always a valve spring upgrade (depending on lift).
I don't think that larger injectors will be needed. You would have to have a recalibrated MAF/PCM to install larger ones. I believe that the stockers are 19lb.
So far, the parts that you have coming look like good items except for the TB spacer. They really don't effect much on these EFI manifolds except for making a whistling noise since the fuel in injected right into the intake port and not at the TB.
