Well its been 5 days since i installed in my truck. Took along time to get and no time to install. First impression was, truck started much smoother and easier. Transmission shifts alot better, firmer. Power wasn't there as much as i thought it would be, but its a 6000lb truck. I definitely need a tune up and O2 sensors replaced. O2's will be done tomorrow and tune up in the next few weeks. And by then im sure i'll feel what its really supposed to feel like. My MPG have gone up slightly, not a whole bunch. Partly cause i dont think ford ever changed the plugs @ 100k.

But overall im very pleased with the xcal2.

 

what motor/year/tunes did you get done? anyother mods? what are your driving habits? city/hwy?

 

98 f150 4.6L V8 4x4 supercab flareside. Only mods an AF1 and mt/r tires. Thats it. Exhaust will be hopefully summer time with new cats;.
