2014 R/T Shaker, Magna exhaust,intune:
Base Dyno 327 whp:356 Torque..
Immediate results are 358 whp and 389 torque.
Going back in this week to "tweak" intune.
Dyno is a DynoJet if matters. I'm happy!
Can't assist with mpg yet-
the type of Dyno does matter, a Dynojet vs a mustang..a mustang dyno puts a load on the vehicle, where a dynojet free spins. a dynojet will show 15hp or so more on average...

if you use the same dyno for the before and after then the increase is what it is.
