428 HP and 454 Torque - 2008 535i


Had a chance to do a before/after dyno comparison on my 535i N54 yesterday. I'm running the BMS DCI, a custom catback system, and a $100 inline fuel pump ( AEM 320 ), holding hi and consistent PSI and factory dp, IC, etc...

To start, we, ( Terry ) ran 91 octane bone stock. Then we added the JB4 G5 ISO, BMS Flash, and 60% E85. Did a few adaption runs on map 5 which peaked out around 410rw. Then we kicked it over to map 7 and pushed it up a bit further. For kicks we ( T ) dialed boost up a bit further using map 6 and picked up a bit more power, but I had an original plug in #6 (I had only replaced 1-5, the 6th plug was broken, waiting for replacement, NGK 5992: Gap - .022 ) which would misfire at high RPM so we ( T ) left boost lower at redline.

W O W !!

I have to give Terry a BIG SHOUT OUT !!
His Tunes are Amazing, his Customer Service is way above par


And here are the pics to go with this Amazing Day !!

Well, at least for me,
