Losing boost in top gears??
Just had a curious question to see if I am the only one who this is happening to, but when I am at WOT I only seem to manage about 15psi but this is like during a race when I go thru the gears. When I go from a roll in 3rd gear or 4th I can hit 22psi just fine and hold about 20. Does this happen to everyone or is this a problem I should be looking into more. I cant seem to hold even 20psi thru all gears. Thanks guys.

RE: Losing boost in top gears??
Im not sure to what extent this applies, but the car isn't gonna boost the same all the time, it depends on torque/engine load. Temperature is a big player too, at least on a stock car. In cooler (denser) air, the car won't actually boost as much, and on a hot day, it'll boost more. Averages out to a set amount of power.
Example of the load situation - My 180 would spike at 18psi, but if i was on a slight hill, in 4th gear from a relatively slow speed, I could get it to climb to 21
