E63 wagon having a good time on the dyno
Car has Weistec plugs, Weistec filters, UPD filter spacer kit, and Eurocharged turbo back downpipes, and running 93octange. Original tune was a Weistec Stage 1 (and for a 91octange state, for whatever difference that may make). First dyno run was 531rwhp @ 4990rpm/578rwtq @4640rpm with those mods and that tune.
Jerry flashed a Stage 2 tune, and next pull was better...except it broke traction on the rollers ha! Someone had a video of the read end wiggling but of course that was the run I filmed from the front. 618rwhp/703rwtq @ 4590rpm, but the readout/graph was all over the place - hard to trust that.
For the 3rd pull, had a couple of guys sit in the back, and Jerry rolled into it it this time to be safe (which you can see on the graph). 629rwhp(!!!) @ 4870rpm /727rwtq @ 3840rpm.
Tried a 4th pull right after, but car was really hot at this point with 3 back to back to back runs. 552rwhp @ 4980rpm /735rwtq @ 2950rpm. Torque up! But lower than the TQ peak should be - assumption is IATs were pulling timing above 3000rpms.
Gave it a couple of minutes to cool off as much as possible so we could get in one last "clean-ish" pull. Jerry was happy with the horsepower and torque curves, along with the AFR - just what he was expecting. 594rwhp/747rwtq at 3960rpm.
End of the day: max numbers were 629rwhp @ 4870rpm and 747rwtq @ 3960rpm. Gotta say, pretty happy with that!

...Ands sounds like a monster too.
Nice day with some cool cars.
im running the same tune on my 14 e63s sedan and ran on ECs dyno with SAE correction factor (so reads even a bit lower than STD here) and made 629awhp/777awtq. Tune, AFE filters, EC catless dp, plugs, 94 octane.
i was on 255 winter tires all around and was also losing traction on the dyno. They said with full traction it would of made even more lol.
Its an amazing tune for this engine no doubt.

And yes, drives great on the street so far. I need to put the resonator back in because it is so damn loud with the downpipes and res delete, but no negatives on the street so far. Traction is....an issue lol. No more power needed (until I get drag radials or something at least ha)
