Winter boost creep problem??
I'm having problems with boost creep. H22, GT30 w .82ar, Tial 46, 3"ex. system with test pipe and dump tube. The Tial has a 11.5 lb spring.
I have a boost guage and a Blitz sbc electronic controller with digital readout. With the control turned down to where it doesn't affect the boost (running off the spring) it boosts to 15 - 15.3 on the gauges. A tuner said that some of it is the gauges and that their mustang dyno unit usually reads a lb. or two less than gauges in the vehicles they run on their dyno.
A counter person said that I'd see more boost creep in the winter because the air is more dense. It's 32 to 45 degrees here. I would think that pressure is pressure and that the WG spring would activate at the 11.5 lb. level whether it was colder or not. Maybe if I had boost creep anyway, more dense air might make it worse??
Anyone with comments or experience on this?

GE intake and Revhard ex.
Earlier after checking the system for leaks, the tuner checked with precision, they changed the sc61 out for a GT30. It was better but could have been leakage @ fittings. I should check the intercooler under pressure next.
