[QUOTE="SCalla1384, post: 13932823, member: 90008"] Btw this is going from boss intake to smoothed runners, lightened steel clutch, neutral profile relearn, and tune (old tune with that setup was 445rwhp) so gains were actually more like 25rwhp on same tune [ATTACH=full]550269[/ATTACH] This 430rwhp (smoothed runners) then getting a neutral profile relearn and the tune , again tune was worth 5rwhp [ATTACH=full]550270[/ATTACH] Looking at those pulls they look VERY similar. I don't think it was a dyno glitch because EJR dynod the same that day as he did a couple months ago. And a catback only GT made 378rwhp same day. So maybe the random misfire was actually causing the car to lose power somewhere where the logs couldn't show it? So you can tell just smoothing and barely opening up the ports on the boss intake helps well. My buddy EJR gained 12rwhp with a aluminum flywheel. Mine is 7lbs heavier. So I'd say at most the flywheel was worth 10rwhp. Smoothed runners was most likely worth upwards of 15rwhp. [/QUOTE]
