Boost level with Stage Kit/Automatic
 

I'm seeing 20+ pounds of boost on my gauge and it's a blast to drive. I notice that when running 80+ and in high gear the boost seems to drop off to about 15 pounds and it feels weaker. Doesn't feel near as strong as in lower gears. Has anyone else experienced this with their Auto? :confused:

Yep, me too. Same thing.20-22 when nailing it off the line. Mine is around 15-17 at 40 mph + and it kicks down and around 19-22 at 40 and below(when I kick it down).

mine will spike to 20-21 and then fall back to 17 or so, and then creep back up to 19... hmmm?

I'm starting to think this is normal as so many people including myself are seeing this.

Yep....and I am beginning to not like it very much. :eek:

Must be built into the GM tune that goes with it....Al

It is normal.

Why Normal? As has been posted the normal tune backs off boost in low gears to save tranny. I would think that we would have all it can give us on the upper end--and instead it feels flat in the 80-up range. If so what can be done to improve it?

Put it in I. From 60mph drop it in I and mash it, i see my boost spike to 20psi and it will continue pulling hard to 24psi let off or switch into D at this time you should be going between 105-110mph

I will give it a try....Sounds like it may work....Al
