<DIV><FONT color=#0000ff><EM>I am new to your forum but it was strongly
suggested by a member of the Xfire forum that I join.</EM></FONT></DIV>
<DIV><FONT color=#0000ff><EM>I recently "upgraded" my 84 Vette Xfire with a
Comp Cam hyd roller 211/218 degree with .488/495 lift at 112 degree lobe

<DIV><FONT color=#0000ff><EM>systems ie 7747 ECM. I also have Extrude Honed
manifold. On a 95 degree day, car ran a 14.3 at 99.7mph and pulled 253
hp@4600rpm/307 lbft@4200rpm at the rear wheels on chassis dyno. This was with
stock configuration chip. I am interested in knowing if anyone has a bin file
for a combination similar to this. I don't doubt that knock Sensor was
causing retard of timing since power went south after 4600rpm. I have a
Needhams EMP-10 burner and would be interested in mainly suggested fuel
and timing calibrations. I believe it is running slightly rich especially at
cold idle strartup and would also like to address dis/engagement of 4+3 OD
unit at higher speeds.</EM></FONT></DIV>
