Great tips, I knew this thread would be helpful.
BTW, I am using the 140 not because I want to make it go super fast. That is not my intention ever.
I have a 140 in my JL viper and I never push it full bore except after a slow pass when I want a strong climbout.
I enjoy strong vert lines and the ability to pull out from near stall speed.
If I see this jet getting fast I will back off, I have nothing to prove.
The other reason is the 140 is more versatile with the different jets it goes in, and now I have two 140s so that opens the door for an a-10 in the next few years if I decide to go that route and the turbines last that long.
