RB turbos on e60 dyno Results- SMS Tune

This car was custom tuned in house on our mustang dyno using only the stock ecu.

Acknowledgements:
I need to shout out to Ken@Wedge Performance for pointing me in the right direction with the boost control pid's.
I also need to shout out to my boy Dave@Savage Motorsports for the 2 hour brainstorming session on Saturday while on the dyno.

Mod List:
RB turbos
ER intercooler
LPFP upgrade
downpipes and exhaust
ER charge pipe
Tial BOV

Stuff it doesn't have:
Meth
Piggyback
COBB


The good stuff:
Dyno sheet shows this car vs. Stock dyno

I meant ignition timing, actual afrs (not tailpipe), basically everything that the ECU is seeing. Unless you are plugging in with an OBD cable or something your not seeing all of the equation.

Yes our dyno has obdII logging.

Being as it's catless and straight pipes we are good with the tail pipe sniffer.

I certainly didn't tune it using my psychic powers

Any cliff notes for boost control via pid tuning? What software did you use to flash the ecu?

We have 3 different tools we use to flash this ecu. One of them writes in 2 min. We also have a hand held device for file switching and remote tuning.

Pid tuning is not quick or easy. In fact it's very revision intensive. That's when that 2 min flash time comes in handy.
