I would suspect the plugs and/or plug wires first. If you are replacing the coils, the OEM coils are hard to beat, stay away from the aftermarket "performance" coils......

I to am looking into after market coils, I've seen articals in Mustang mags claiming 5hp increase on the 4-tower version (I have a 98) and as much as 15hp on the coil on plug versions. Now I know that all sounds ridiculous, but they post dyno data. I'd really like to know someone whos done it on a 150. Any one out there actually try it?

if a COP fires each time on compression, and you have no miss, what "increase in performance" are you going to get? The stock coils will easly fire at 5000 RPM on a stock engine and i dont think you want to do that continuously on your motor. at 2000 rpm it should be fine. if it misses at 80 MPH i would look more at the fuel , etc.

I don't disagree, this is why I am asking where they are getting the increase. My F150 is a 98 and is not COP anyway but even the 5 hp from the four tower version would be worth it. The dyno dosn't lie either, but I'd sure like some verification before I spend the money. I'm not really concerned with a miss, it's time for plugs and maybe wires so I figured now would be a good time to do coils too if there is something to be gained.
