JB4 cars ran deep in the 11's and trapped 116-120+mph.
JB4 is already discounted around 50% of the price of a flash tune.
However,
JB4 will not remove the top speed governor, eliminate a cat-less DP CEL, do burnout mode, burble or gargle.
Hey i was just wondering if you were running the ARMY TRIX DOWNPIPES with the stock exhaust ?

I am looking for some performance and sound upgrade, something that can be switched back to stock when my lease becomes due. Had experience with OE Tuning, did the ECU remapping on a 2016 e400, liked it a lot, just wish I could switch that tune to my next car.
