Ill post a picture of the dyno when i get to a scanner but for now...
266 hp and 275 tq with the cutout closed
267 hp and 279 tq cutout open
SAE corrected .97%
that may be right for what I have but Im kinda dissapointed.. he also didnt do the thing where you bring it up to 50 and then stomp on it so it doesnt downshift (I heard thats what you do on autos). He said he was rolling on it so it wouldnt downshift
i highlighted the main points in my cars set up

yea it was a dyno jet.. after a little math knowing the SAE correcting it comes out to
275hp and 287 torque
i was told if you divide the number by the SAE (.97 in my case) it gives you the real number.. i dunno thats just what i was told

Well, although some will disagree, I think you would benefit from boring out your throttle body. Mine woke my car up and I probably gained 15hp (SOTP testing). Plus, there is ~15% loss through the transmission (IIRC).

If you divide it by .97 you get the actual HP #, but everyone goes by SAE so you made what it says on the graph. And dyno #'s really don't mean ****, go to the track to post times. Also cheap restalled converters hurt more than they help.
