but a 5psi drop is alot for a donut leak, if it was a donut he should hear it in the cab and/or see lots of soot. as madvan said, check the map line, and if thats ok try unplugging it and driving the truck with the map sensor wire unplugged.

ok no abnormal sounds, and definately no soot, so i'm pretty sure it's not exhaust. I rechecked all of my connections and found a cracked piece on the tee setup. so i fixed that, and now i'm back to seeing 15 psi, and the power i had lost is back.
So is 15 psi still too abnormal? or am i not the only one with a stock truck that peaks there?

thanks bill.
I have heard as much as 18-20 stock, but at 15 psi it runs great so i'm under the impression that it's fine.
6637 got here today. how much boost should that add???
Thanks guys! your help is invaluable.

this video has poor quality but its taken with my digital camera while driving... on the gauge you can see an inner set of numbers in red, the first line is 10 psi and the second line is 20 psi.
