kinda irrelevant, consider it a bump.
but how much HP you puttin' down with 21psi?

 

is tuned for 21peak and it hits it well on a good cold day,but 19 and 20 most of the time. it dynoed at 280 to the wheels but apparently they had problems w the dyno so numbers might have read low. i did some more upgrades after that so it does feel better than how it did for 280 for sure
