[QUOTE="Jam421, post: 15996806, member: 110985"] VMP67 vs KB160 Mono Blade TB +34rwhp: Attached 2 dyno sheets. The only mod being swap of VMP67 w/BPS O-Sized Plenum to the PBH Package KB Mono Blade + XBA (bolt match) O-Sized Plenum+JLT 148CAI. Both plenums are made by BPS so that's a wash. JLT148 replaced JLT127. HP increased 34RW. BIG diff was Torque #'s stayed very much the same (679 vs 680).. BUT....the power curve came in harder, stayed flat longer. And...Oh Boy do I feel it everywhere from 2800-redline. Despite the KB Mono upgrade boost remained mostly same 16.3 vs.16.5psi. Both dynos were done at same shop, similar temps, 3yrs apart thru 410's. My car is Lund Race Tuned. Swap to KB Mono was also Lund advised after 2 failed SCJ tuning experiments...which DID show 17rw gain on 1st pull but could not be driven. I do follow Lund's advice adding 1/2 bottle VP Octanium per tank simply because our 93 octane area fuel seemed not to be consistent on Data Logs. Driveability is like stock. Idle is steady at 850rpm. Off idle around town smooth & stable. No "tip-in" stumble/wrench light issues as with my 2 SCJ's. Anywhere as low as 2200rpm on stab is linear to redline...no surge I keep thinking I'm near the max of my stock motor. But ..after reading some of the comments here I may consider a lower 10% to bump up boost from 16.5 to approx 18.5psi....OR...as I also plan to upgrade OPG I might just have the Stock Trinity ported porting instead of the lower 10%.
