boost leak in Bov???

[g2ic02]

i swapped a t28 on my redtop, I have an hks actuator set at 13-14psi...when i pull in 4th gear and it gets to about 14psi it starts to backfire, but only on colder days. When it is warm out it will pull all the way to 7000 with no issues...i am guessing it is a boost leak, or a fuel cut issue. Also my plugs are gapped a little wide .039 i guess this could also be the culprit.

What i am wondering is what psi are greddy type S's rated for...I have all my intercooler piping t-bolt clamped so i am gonna assume it isn't leaking from any of the couplers..

Thanks for any help.

i would try to gap it bak down to .030 and the type s bov is good enough for your power level. Not sure what the limit is but i have the rs

gapped my plugs down to around .030 seems to be alright, I was wondering what is the stock boost cut set at, or is there even one on our cars?
