i will agree, with stock heads, it works great! i am another happy one with the MS4... but watch out, you will push your stock fuel system beyond max... and that will hold you back from making the full power the cam can make. at least thats my problem right now.

well, i have a 6.0Litter head I don't know how big the gasket is though. The only upgrade to my Fuel system is the pump (Wahlbro 255lph In Tank Fuel Pump) do you mean upgrade the injectors? BTW the cam that is in there right now is a TSP 231/237. I'm not sure of the lift or LSA

yea, i ment to say injectors... working 12 hour days, make your mind go crazy!

anyways, i am reving the **** out of mine, but i got those damned 12 point headed rod bolts

I got the high end of my tune back down some till i get my fuel system done here shortly, and it still ended up running the times in my sig... great job TSP! my F-11 would never have ran that fast! small cam nut swingers go home!

I have the MS4 and I am just waiting on my headers, intake and machine work on heads( valve angle job and porting). I am upgrading the intake pump and going with 36lb injectors, with bigger rails. You all think my fuel system will be ok?

well my injectors were the first to show, 110% duty cycle... but i'd say the stock pump wont be far behind...
