New h&s update produces high boost numbers

[giwhop]

Is it just my imagination or does the new update make alot more boost?I can be driving along at 65 mph and give my truck 1/4 throttle and the boost will spike up past 40lbs is everybody experiencing this?

I thought it was just me! I thought I had an exhaust leak or turbo leak. I had my defuel set at like 38 and while I'm accelerating at like 25-30% throttle I'm defueling.

Are you talking about 6.4.46?

I just put in my dpf delete and thus my dpf delete tunes on saturday. I can be cruising and go to pass someone under light to moderate acceleration and im defueling at 40 psi as well. I had nothing to gauge it off of thoguh as this newer revision was my first go around with the deleted tune file.

40psi is no issue for a 6.4 IMO

What's different about it? It worth the update?
