How much boost with cold air
How much does boost increase with cold temps? I have a kB with a 7psi pulley and it hit 11 psi today at the shift. It seems to have lots of power b/c it spun all the way through first gear and got sideways. Is 11psi with water injection too much for a stock 5.4?

Any temp below 60 degrees and my L, with KB, dialed for 16 lbs will easily reach a solid 18lbs. Lets just say I watch the dial very closely on the cooler evenings. Trying to avoid the boom factor.
