Ok, I changed my mind and made one more pull on Sunday. This time I added boost in stages and it ran out smoother. I think the turbos were getting close to the surge line when boost would come in as quick as possible. These things hit hard! Anyhow, boost was set at 20, but hit 22, then dropped to 20, then I bumped it to 22, then 24. I wanted to go higher, but the dyno was only set to log to 140 mph and the pull was done too quick. The chart showed a 30whp gain on the bump from 22 to 24, so power is still increasing nicely at that level. It is also more than 120whp higher then how we ran it last week trapping 146 mph.
