Hello all, HG Motorsports here in San Diego had GSR come down to flash my ECU.
I have a '14 N55
ER Downpipe/charge pipe.
6MT
Stock Intake
91 Octane
The dyno shows:
"stock" - no tune, only downpipe
JB4 map 5
GSR custom tune
The JB4 provided amazing results, especially for the price. I probably would have kept it if i had 93 octane available.
I'm very happy with the results from GSR, thanks guys!
On a side note, they also flashed my buddies GL63 AMG
Lets keep this thread clean.....
