[QUOTE="ridge68, post: 14077977, member: 160571"] I recently installed the VMP 2.5 stock look pulley and 90mm idler package on my 2012 GT500, along with one step colder Motorcraft plugs that VMP lists on their site. I already had installed a Steeda 113mm cold air kit, Corsa Extreme mufflers that I kept from my 11 GT/CS, along with a Steeda tune. I received an updated tune for the 2.5 pulley, also from Steeda. The car is relatively low mileage, around 10k. Why am I only seeing 10 psi on the boost gauge? From what I read, I should be seeing 12-14psi...any ideas? Your thoughts would be greatly appreciated!!!
