DYno sheet

RE: DYno sheet
Those are some good numbers. I noticed on your first two runs the air/fuel ratio was a little lean until about5000rpms and then came down to 13.0 from 5000-6500rpms. On the 307rwhp third run the air/fuel mixture was adjusted to right at 13.0 all the way accross the band from 3000-6500rpms. Who made these adjustments to the air/fuel ratio you or speed inc and did they save the adjustments as a custom tune. The reason i ask is becasue i have a buddy with the same exact mods and tuner and he made 305rwhp and 316rwtq but he had to adjust the air/fuel on racer tune just as you did to geta/fright at13.1-.13.2 at the tailpipes. I believe the canned racer tune is dead on 13.0 with just the racer cai and with the addition of the x-pipe and shorty headers caused the a/f ratio to lean out just a little and minor adjustments were needed to be made to the canned racer tune.

Shorty headers are no better than have stock manifolds. Need to get some long tubes. I just installed a set of dynatech longtubes with catted x-pipe into my borla stingers. Dynoed before the headers at 305rwhp and now im at 318rwhp with a diablo tune from FC customs.
