so what boost controller are you using ???

It's part of the Holley Dominator EFI ECU.

ok Im not sure how that one sets up but on the one I used it worked best by ramping up in small quick steps --all in by a second or less

Were you adding/removing fuel and/or Timing?

the boost controller was adding pressure to the back side of the waist gate in small increasing amounts very quickly -- the fuel pressure regulator added fuel based on boost pressure ie boost referenced and if I remember right timing was at about 25 degrees over 12-15 lb boost . Boost controller setup was 12lb springs in the waste gates and then every lb of c02 on the back side of the gate increased boost by aprox a lb -- data recorder will tell you exactly how much.

Yeah, we're using co2 on the dome to control boost pressure, that's under control. We're currently not ramping in the boost after launch as the chassis has been able handle the current boost level.

What I'd like to be able to do is spool up faster on the t-brake.
After retarding timing while on the t-brake, we're able to build more boost, went from 6 to 11lb. We have one run so far with the launch increase. The datalogs indicate the converter is too loose, we were out of rpm 6.6 seconds into the run.

Cool very easy then. Just messy! lol I just changed my stator this weekend. I have a 9.5 ptc bolt together.
