How accurate is the boost gauge in the 09 500? Reason I ask is i just did the JLT combo and now I get up to 15psi in boost using a 2.6 pulley. Is this possible? I something jacked up?:shrug:
Got 11-12 with just my 2.6 pulley. Stock guage bottoms out after my lower install. I would say that is close, but the stock guage accuracy is not good.
