How to set the timing

It wont run correctly til you tune it. Although depending on the heads, the F cam isnt THAT much larger of a cam then a stock one. It might have been fine with just the heads. Hope you checked PTV clearance.

you can get that thing to run good with out a tune just messing around with fuel pressure and timing and have the correct injectors with the correct maf sensor housing for the injectors.i personally thing paying some 1 to tune and burn a chip is a waste when u can just buy a computer and plug it into your lap top and tuen it every time you do a mod rather then get a chip burn every time.plus if u get nitrous or a sc all u gotta do is plug in to the car and tune it.f cam is alot bigger then a stock the stock is like .440 lift and the f is
.512 and alot more duration.

Stock HO - .444/.444 lift, 204/204* @ 0.50
FMS B303 - .480/.480 lift, 224/224* @ 0.50
FMS E303 - .498/.498 lift, 220/220* @ 0.50
FMS F303 - .512/.512 lift, 226/226* @ 0.50
FMS X303 - .542/.542 lift, 224/224* @ 0.50

There is a huge difference between the stock HO and F303 camshafts.
