Default Boost and twin turbo question - 05-17-2015, 03:54 PM

So is boost suppose to drop around 2500-3000 rom?
And when ever I floor the car, is the boost suppose to build to 15PSI (JB4 map 2) and then the turbos kick in? It seems like sometimes I floor it and the power/boost builds up to full power, where as other times all of it kicks in at once.

Depending on RPM the turbos will spool faster or slower, you should Google "how turbo engine works" lol
