im thinking its on the dot for 93 octane, and pushing it for 91

 

what octane of gas are you running?

 

get a alky kit and you will be fine. Im pushing 29-30psi.

 

its kinda high i wouldn't want anything over 22.5 on pump

 

the spiking is fine. your boost is just about right.

 

How are you reading your boost? If you are using a gauge, then more than likely your gauge is about 1-2 psi off. Assuming 1.5 psi off, then you are spiking to about 22 psi and holding at 20 psi. Where is the boost gauge by redline?

 

He is right there is no boost gauge that reads the right boost unless its a boost log or a dig. gauge so that means your really only running 21 spike and droping down to 18-19.
