Just got back from the dyno. The 77 mm Pro-M i added gave me 11 hp to 283, and 281 RWTQ. I had the air/fuel read and am running EXTREMELY rich, about 10:1 at around 3k and levels off at about 11.5:1 at 7 k.

I am thinking of getting a chip burned to lean me out a little, and with pullies, hopefully I'll be knocking on the 300 hp door!

Good numbers. Last time I dynoed I pulled 273hp and 274 tq with Mac CAI, Mac Hi Flow H, 2 chamber Flows, and Royal Purple synthetic oil. And before anyone says RP isn't a HP mod, we dyno tested it on an F-150 and it gained 4 horses at the wheel.

Well since then I've added Steeda UD's, Steeda T/A, and also changed to an O/R H so hopefully I'll be knocking on the 300 HP door also:thumbsup:

Just got the chip installed. Will take to the dyno within the week. I'll post the numbers when I get them. This chip looks pretty cool. It has four programs. Each one bumps timing and leans the mixture. Should be interesting. Stay tuned.:)

This may be a stupid question but can't you adjust your factory computer to lean out the mixture?:(

I can't but the chip can.
