well, last night my friend(the guy from the previous thread) and i drove over to Stiegemeier's for my dyno tune. i made 4 runs all together. the first was good, until about 4500 when it started knocking a little(i didn't even hear it). we looked at the numbers and saw 429 hp and 379 tq. more importantly however, the timing jumped to 22° up top, not good. we backed it down to 17° across the board and adjusted the AF a little and made a second pull. this time 476 hp and 403 tq. Bob was speechless. these numbers were comming from a stock pullied eaton. next run was about the same with some minor AF changes in which i made the biggest number of 479 hp and 405 tq. i wanted to go a little safer with the tune(it was already on the safe side anyway). so we backed to 16° timing across the board and richened a hair across the board to get an AF ratio around 11.2-11.4. we made one last pull and were rewarded with 470 hp and 402 tq. 
that is the final sheet below. that little dip at around 5500 was leaned out just a hair to bring it to the upper 10's before we called it a night. Bob and Jim were very impressed with how much difference some compression makes on blown setup with these cars. Bob said he might put some pics and numbers from my car on his site, so that had me smiling too.
driving impressions afterwards, well, let's just say undescribeable! this thing pulls like one strong MF! i am absolutely amazed! :thumbsup: :thumbsup: it is now a totally different car. punch it it any gear at any speed and it flat out runs! i am still catching my breath....
i do have dyno vids by the way. i will post up later after i get them from my friend. we'll see about making a couple other quick little vids as well.
as for the blower whine for those who were wondering: it SCREAMS! another friend was getting gas and i did a drop to second and hammer it as i drove by. he said it sounded almost as loud as his lightning with a 2.8 upper and 2lb. lower!
by the way, my mods are in sig as well.
