The duration of cam #1 is too small and cam #2 is WAY too high. Dont run either with a turbo. You need something around 225/225 duration on about a 590 lift and 114 LSA if not more. I wouldnt go any more than about 230 for duration. Some like split duration but depends on whom you go with for a cam.

Thanks for the input...unfortunately Cam B is currently in (from before Turbo) and Cam A was a choice because it is free $. Cam B has good power from roll but will not spin INVO 295's from stop with out brake boosting
Tune has been optimized but Cam B just not too compatible with this config. Will just have to chose battle situations carefully
for now.
