I have observed that while on the dyno the boost hits hard and then drops off over 5K. Is this normal?
Thought this TVS blower was good for 16+ psig and didn't expect a drop off at this level of boost.
It made about 13.5 and drops off to 11.
Car made 601/617 with just the pulley kit and some minor tune changes. Will post sheet when I get a chance.
