i got a buddy with a 07 gt500 and wont go past 5 psi of boost is this normal? whats the stock boost reading & with a cold air what would be the boost increase if any? any help would be appriecated.
mine reads 9psi bone stock.
Problem was the tune.:bash:For not going with someone with GT500 experience.
High humidity will result in slightly lower boost numbers, but not 5psi. I didn't think the tune could adjust boost. Learn something new every day.its been very humid in the area would this contribute to the boost loss to 5lbs? its a bone stock 07 gt500 for the exception of a cai and tune for it.
humidity is not the culprit, it's actually a little blessing.
what will bring it down is altitude and temperture.
I'm in midland 2800'msl and at about 95* my boost is reduced from around 8psi to 6psi
I have about 300 miles on my '09 and the last time I had it out I was seeing about 6lbs of boost. The elevation here in El Paso is around 3,700' above see level. Temps are ridiculous out here. Does that seem about right for boost? Funny thing is I would see about 5-6lbs on my '04 and as high as 7-8lbs in the winter.
