23psi spike, should I be worried?
So I installed my Hallman ES boost controller today and every gear except for 5th spikes up no higher than 21psi then goes to 20psi. 5th gear spikes to 23psi for a second then drops to 20psi, according to my Defi D boost gauge. Should I be concerned about this or can I let it slide and be okay?

Boost Spike
I have same exact setup on 93 octane and experience same spike you are in 5th.
But I am not worried. Tried a slight adjustment down but then you drop to 19PSI and it still spikes. Could be lack of back pressure from running a 3'' exhaust system.
