So dyno'ed the beast a second time today...as some remember I dyno'ed 4 weeks ago on a dynojet, tach p/u issues, came in with hi # of 401whp-eurocharged. Post 1st dyno I added milltek catback, hyperboost DV, AcesIV. Took the beast to a diff shop today, mustang dyno.....2 pulls flash, 2 pulls stock......datalogged all. The best # whp on flash was 332whp and best tq was 376. The stock #'s, best whp was 333 and tq was 335. Go figure, not sure why the HP #'s were the same, the TQ #'s had sig delta. I know there is a diff between dynojet and mustang but that variance is huge.....funny thing is when I reflashed back to the eurocharged, waited about 30 minutes, engine was cold, ambient temp was 45 degrees...we ran a 3rd pull at very end, and the whp was 312, and tq was 323.....scratching head....

Don't get all worked up over dyno numbers, especially when you switch dyno's. I dyno'd mine yesterday on a Mustang. 318/404, bone stock. Gonna flash it and go back to the same dyno. Going to another dyno would mean nothing. If you are going to switch dyno's, use real world numbers to test your performance, like Vagcom, PBox, trapspeed/timeslip, etc....

I did vag log, Dave hall has copy. The numbers looked great, exactly like the 401whp dyno

Even the same dyno can cause discrepancies in numbers. I dyno'd 444whp and 528w/tq. with the eurocharged tune, but had consistent 0-60 times of 4.7, and 60-90 times of 3.9. I went to the same dyno with my Viper tune and pulled 414whp and 444w/tq, but was running consistant 0-60 times of 4.2, and 60-90 times of 3.75. I knew the Viper tune was faster, but the Dyno let me down big time.

i would love to see your graph and see where the torque came in at

All of my dyno graphs, as well as all of my acceleration times are on the site somewhere. The dyno runs from my early Eurocharged flash were hog wash though. I think the peak torque came on at 3400, but those runs were irrelevant.

I will do a search and find them as i'd like to see where your torque came in and stayed till, I know with a Greedy controller you can control the Torque, as with my Porsche if i have it a 5% gain it is 670 fpt and 15% it shoots up to 755.. Be interesting to see how all the tuners do there magic
