[QUOTE="CaliGT500524, post: 16320672, member: 185428"] Yeah, somewhere in that range. IronTerp posted this on a thread detailing step-by-step mods and dyno runs. The runs were on different dynos and probably different days, but the gains seem to be beyond just deviations, I could be wrong. Of course, I was stating the gains in the context of my setup as what I've got is very close to his setup (and maybe a tad bit better because of my fueling mods). He saw essentially +10whp going from a ported (so not even stock) 60mm stock throttle body to a Ford Racing 65mm: 577 to 586. Then he recorded an additional +17whp going from the 65 Ford Racing TB + other mods (while just changing the throttle body and no tune mods) to the VMP 67mm: 591 to 608. "Definitely worth it to go the ported Eaton route. - With a Posi port, ported stock TB, JLT 110, 2.40" upper, and 20 degrees of advance, my 07' hit 577/552 on Lee Blankenship's Dyno - Upgraded the TB to a Ford Racing 65mm and hit 586/574. Same Dyno. - Upgraded the JLT 110 to a JLT 123 and hit 595/582. Same Dyno. - Re-tune with the same setup netted 591/579 on Johnny Lightning's Dyno. Upped the timing to 21 degrees for this session - Added a VMP 67mm throttle body with no tuning adjustments and hit 608/581 on Keith's Pit Stop's dyno." Do you interpret that differently? -Adam [/QUOTE]
