MAF or no?
i never had that particular engine, but i had the FIPK on my old 90 F150 4.9L. i loved it! i didn't ever dyno it or anything, but it was pretty obvious that the truck enjoyed the extra power. i have some long hills/mountains around here that i could never go up w/o having to downshift and rev the snot out of it just to keep speed. with the FIPK, i could just roll my foot into it and leave it in 5th. i could get up just about anything with ease. as far as MPG, i didn't notice any HUGE gains, but i didn't notice any drops, either.
i liked the FIPK enough to order it up for my "new" truck, an 89 F250 5.8L
hope this helps,
Mike

I have the speed Density system
My truck has the two small tubes, so speed density system. Has anyone tried the K&N kit or a homemade kit on the speed density system? I have looked into the banks powerpak upgrade but, can't spare the $1800 right now. Thinking about deleting the cats and upgrading the air intake to see if I can get a slight mpg increase and increase performance. Any suggestions would be appreciated!

saay what?
mine has 1 large tube feeding 2 small ones. look for the MAF sensor between the throttle body and the air cleaner box. square looking flat thing w/4 or 5 wires going to it. if you got one of those its MAF if not its speed density.
