Hi all,

I went to a track day at Wakefield in December. Twice my Defi gauge controller emitted the warning alarm in regards to boost pressure. Im running 9psi and I have the threshold at 10 psi. I was getting boost creep, well Im sure it is.

Immediately I did a cool down lap, gave it another beating and no problem.

What would cause this? Doesnt boost creep arise from a WG that cannot flow enough?
I've decided that heat was a big issue, but I dont see how that can affect the WG.
I dont think its the boost controller either Im running a HKS evc5

Any help would be greatly appreciated.
