OE Tuning - Flash tune for 535 N55

For those of you out in CA OE Tuning might be another good option for tuning your 535. It is a flash tune that they have to do in house with pretty good gains. Not the best if you are out of state since you have to remove your ecu and send it out to them for bench flash it. I'm not even sure where the ecu is located on the F10 but i heard its mounted under the intake manifold so its a pain in the ass to even take out.

Here's an email that i got from OE Tuning regarding the N55:

From tuning we typically seen gains of +50-60wTq & +40-45wHp to the wheels from dyno testing. The price for the tune is $695.
Features of the tune include:

- Higher Torque request
- Increased Boot Pressure
- Improved throttle response
- Ignition & Fuel adjustment
- Rpm and shifting limits can also be increased

The ECU must be removed and sent in for tuning. All ECUs are modified and sent back the same day as arrival. Total turn around time is 48 hours when overnight shipping is used both ways. Please include a return label with your ECU. Your tune will be saved in our database and is always 100% reversible.

Best Regards,

Josh


Peak HP and TQ seems to be on par with the JB4 but you can tweak more things with a flash than a piggyback could (throttle response, timing etc..)
