+1Like we discussed during our holiday party - If the high boost level is more than a spike then you do not have the supporting mods to support the fueling.
Taking a data log and sending it to your tuner is the best first step

Is that a tune you drive on the street or track?So I got a custome tune done from a shop in Mass. I was logging 21lbs of boost when flat out and my only mods are intakes, midpipe and catback. A lot of my GT-R buddies said it was unsafe! Any thoughts?
