[QUOTE="Jam421, post: 15673968, member: 110985"] Geeze....I was thinking my boost psi was 16.5-17 but realized yesterday on a no-tune dyno pull my dash boost gauge was typically not accurate . Boost was actually: 6000rpm = 15.2 6200rpm = 15.4 6300rpm = 15.5 6400rpm = 15.7 6500rpm = 15.8 6600rpm = 16.0 6800rpm = 16.3 Based on this 70 degree day dyno info I'm thinking 10% lower....keeping the 2.4 upper and pulling the stick sooner....at 62-6400 . Okay boys........ Ready to be told it's a stupid idea ! ps: Lund Tune. I will be contacting Lund Monday morning for their guidance. [/QUOTE]
