Are you missing pulleys on the mod list? 75 HP from intake, TB and long tubes is a lot.

Yes 93 pump gas. I was pleasantly surprised when I heard the number.
Not missing any HP mods on the list. I have Girodisc brake rotors which are lighter than stock so maybe some difference there? It's corrected but regardless it was cool air so I'm sure that made a difference as well. The dyno tune was this past Wednesday 5/1/19 in Cream Ridge, NJ at 11:30 AM if anyone cares to figure out the DA. I do not have a stock baseline for comparison either.

Did you pickup any power with the Halltech? Considering making the same switch as you, and I have the same mods.

Halltech is the best. Yes, 15+whp more. Torque showed the same or dropped, which I don't believe. I'll post dyno if I can remember. I may cut out primary cats soon for a little more, well see.

It was at ECS. I did all the work myself except for the headers because I don't think I had enough room to get them on without a lift so I had my local mechanic put those on for me. I took a trip down to ECS after and Doug did my tune. I thought I heard wrong after the pull when he said the numbers then I read them off the screen with my own eyes. Definitely had great air that day so I'm sure that played a part despite the correction factor but ECS is well known for good results.

I have a 2019 M7, put on the rollers (dynojet) when it had about 1000 miles on it. Running 93 octane, only power mods are BMS filter and Mamo PTB, but out 589 rear wheel. Mods had been on the car for over 200 miles driving prior to the dyno test. Concentrating now on getting some weight off the car which weighed in at 3534 lbs on race shop scales, nearly full of fuel. Weight reductions will take it well below 3500 lbs, including reduction of 29 lbs of unsprung rotational weight. Not interested in losing the warranty...
