MHP Stage I Dyno Results, and Vid v cam'd LS1/RX7
Just got back from the dyno. The runs posted below are 5th gear (1:1) SAE corrected, hood down, using the same dynojet I always use. I made one pull in 4th gear after and made 433rwhp/383rwtq (+6rwhp and -10rwtq over 5th gear).
427rwhp/394rwtq SAE (Using 17.5% DT loss that's 518hp/478tq @ the flywheel, using 20% DT loss 534hp/493tq):
Compared to stock (sorry no TQ #s for stock since we had to splice into the coil pack wiring today to get the wire isolated, there will be TQ #s from here on out):
As far as I know our V1 tuning just beat every other C63 ECU reflash on the market, and the best part is A/F actually dipped into the 11s at 5800rpm meaning there's an easy 15-18rwhp (a tad more timing in v2 as well) left in the car in a SAFE revision.
For frame of reference look at Rentech's results in 4th gear (producing higher #s than 5th):
Using my 5th gear numbers we're making 33rwtq SAE (counting the 10rwtq I lost going from 4th v 5th gear dynos that's 23rwtq SAE actual) and 15rwhp SAE (counting the +6rwhp loss I saw going from 4th to 5th that's 21rwhp SAE actual), and again we have another 15-18rw coming in v2.
Using my 4th gear numbers (direct comparison) we're up 20rwhp/23rwtq SAE on them.
Finally, me running a 2700lb cam'd LS1/RX7 on the way home, the owner who lives less than a mile from me says it traps 115-116 N/A (how we ran today). He jumped out 1 car from a 20 roll before I hit it.:

So again, I'm calling it right now. We'll be at ~440rw SAE in 5th gear on a DJ with v2, and we should also breach 400rwtq SAE as well with just filters/tuning on a 2400 mile C63.
Renntech, Kleeman, Brabus, whoever, I'll make the offer to run against a similarly modded car of yours ANY day.
Thanks

Was it a Mustang dyno? If so that makes sense. Either way take it to the track to get some times, another guy just ran 11.4 @130 on race gas in his EC tune only car with no downpipes. Curious to see what you'll run.

The C63 you speak of has the Biturbo 4.0L M177: https://mbworld.org/forums/c63-c63s-amg-215/
