Default Max boost with UTEC stage 1 and ABC fully closed

I put in my utec today and love the smooth acceleration. I was surprised that with the ABC fully closed, I was only getting approx 14.5 psi. The utec user manual says that at sea level (where I am), that I should get approx 15.5 psi at sea level. What are other people getting with their ABC fully closed?

At a tad bit above sea level (Chicago), I am in the 15's running closed loop boost control without the ABC.

Take a wild guess


Rich10, I'm getting exactly what you're getting with the ABC fully closed, on 4th gear WOT. I think that's pretty much what the factory setting is. When I open the ABC one turn, boost spikes appear, especially on 5th going partial to WOT, and boost can go up to about 17. That's where close loop can help you.

I'm near sea level, and winter air also helps to turn up the boost.
