The entire site is doing this not just the ZL1 subforum.

Yeah I noticed that too and it's showing there are posts but it's not showing which ones have been updated. Outdated forum junk issues probably.

Socal, nice chart on the boost.

Did you have any comparison vs. the 2.5 upper pulley? my guess is 10 or 11lbs?

Hey buddy, I dont... I put a 2.4" pulley on when the blower was ported the first time around... I would assume a similar step down, as it was up.

I will also update the chart once finished with tuning, and I can do some more pulls from 2,500 to redline with the new set up... currently only doing street pulls in 3rd gear going up grades in order to keep the top speed low. I'll do a top of 4th pull soon when I can find the right road / time...

That's the way I do my tuning for the exact same reason. Up a hill in 3rd gear to get it right, then verify on a 4th gear pull in a controlled environment.

I think I've always done my pulls the same way. Up and incline, locked in 4th (automatic), from 40-100. Lately just to ensure fuel pressure integrity all the way through under an extended load I have been doing pulls from 25-100 in 4th under WOT up an incline. That has shown me any and all prevalent issues that may be hiding either in fueling, timing or anything else that I might be blanking out on right now.
