Well, I ran 258 to all wheels, and only 223 ft lbs of torque. I believe that since he is only pulling fuel to tune, he is fighting the stock ecu's retarted timing...thus giving those low torque numbers. More boost + less fuel to lean her out I believe has much less of an effect on power/tq then advancing the timing and keeping an eye on the fuel. I think that in this case, the stock ecu is your enemy.
I am not trying to be a know it all, this is what my research has lead me to believe. Not a definative answer...but a very good and researched educated guess.
I also feel that the HP tq conversions are crap... Just my $.02 and not scientific.
Good power with just using fuel and boost to tune...amazing!!! I have very similar mods...and am looking into the S AFC for a temp fix...
