I'm quite sure that it is quicker at the higher boost settings at higher RPM but there is noticeably more lag the higher I went over stock boost.
Diesel I think I asked you this before but what octane gas are you running? I'm going in to get some more dyno pulls done at higher boost and higher octane gas this week.

It has been really hot here and any forced induction vehicle suffers after about 85 degrees in my humble experience.
LGK - What exhaust system are you getting? Its been so hard trying to source any exhaust system. Even the custom muffler shops worth looking at in socal are booked over 2 weeks out!

I cant wait to see how this all works and what the dyno numbers look like at all the different boost settings.

By the way Diesel do you know what the maximum or limit of the JB Stage 1 boost is set at?
