14psi pull on a 2.5 s60

Last run was at 12tdc timing, 14psi. FWD stg 3bar cal running on a 2bar sensor:confused:
Stock 2.5 bottom re-ringed to repair prior booboo.:bash: removed the balance shafts while in there.:thumb:
Mods are cam timing advanced 4degrees, super 60 turbo, +40s, tu 3in sv, 3in downpipe, self ported swirl head with +1mm ex valves, self ported exhaust manifold, fmic, 3inch charge pipes, untouched 2piece intake and stock throttle body. 91octane pump.

Numbers seem pretty good to me considering the lowish boost and it was through a 3inch exhaust pipe 3in catco and a 3inch dynomax straight through, sucking through a 8inch long K&N cone filter on a 3inch intake pipe. Once I get the fwd cal to read the 3bar map we will see what it can do at 25psi. :thumb:

higher hp than I made at 12psi but I made 280ft-lbs.
those #'s were way before where I'm at now. They were a stock 2.5 with a 2 piece, ported exhaust manny, .63 housing, 2.5" SV, 3" straight pipe/side exit and cummins i/c.

PS for the naysayer about our cals: Our cals are excellent, and yea there will always be a few people that may not 100% satisified, but alot has to do with their set-up and tuning as much as the cal itself. Our cals are in the fastest t-3 (wallace 11.68 and 427whp), the fastest 8v in Canada (shadow 10.99 eta) and hundreds (and maybe thousands at this point) of other racers and daily drivers alike. We wouldn't still be in business if our cals were that bad.....If your friend actually owns one of our cals and is having issues, tell him to call me.
I don't really think you can count Shadow's car as he's running a 4 bar map on your 3 bar cal which while it makes power is not what the cal was designed for since it puts all the fueling and timing tables that much more offset.

Your cals have seem to have gotten better though. I remember the days of people driving their cars around the block on your cals and the engine's blowing up. Then you turned down all the timing and flooded the cars with gas. But it seems like you guys are learning quite a bit with the dyno.
