What meth kit? lol, how will they know? They don't go into boost and it's fairly hidden. Like the Nitrous, it's for track use only, lol.

As far as 13lbs With a 3" pulley I'll be at ~10lbs. and make a few more ponies.

With the hptuners...what kpa reading are you getting?

That 400hp number is old I haven't had it on a dyno in a while.
I have a Autometer electric boost gauge and it records the highest boost seen, it shows 13psi, the most KPA I have logged is 187kpa, the Gauge may read a little high I don't know. As far as restriction I am runing stock cam, stock heads,and shorty SLP headers, Magnaflow cats and mufflers.

Attached is a log file I did yesterday 85* day at 30.03 baro look at frame 5830 it shows 184.75kpa BTW the far right row is kpa and next to it is AFR.

Here is the HPTuner .hpl scanner file for those with HPtuners.

I punched it in secound gear At 40mph (frame 5569) and ran it up to 120mph(frame 5966) Note that in the top of second gear (frame 5830) 184kpa was acheived and this was a 85deg day, in the winter on a 40deg day I have seen 196kpa.
and BTW when I did my RamAir hood and Ram Air lower duct I did see more boost almost a psi at 100mph.

These are wise words to follow, too bad I had to learn that one on my own!

10 psi on the 5.3L with a turbo or blower with meth will be fine and last you as long as you need, tranny is another story though.
