I don't know about HP but I did gain almost 2 MPG with interstate driving(70-80 MPH)

We have had stock ZL1s dyno from 525-570rwhp on our dynojet. The 525 was a bit of an outlier and only had 500 miles on it at the time. After a few dyno passes it started pulling a lot better. Unfortunately we don't get to many people adding just an intake so we don't have any before/after numbers with an intake only. We have tested the Big Gulp upgrade and made 30rwhp over the standard Roto-Fab (dry filter) and a competitors tune.

We have seen ~15rwhp with the gateway mods (Roto-Fab and ported throttle body)
