Yet another ecu which was tuned by another tuner using way to much fuel and and boost
Also missed a lot of the main limiters which hold back power

Customer brought his car in for us to remap it
Testing it on the dyno we found it was not standard and making 291bhp and 450ft (green line)

On looking at the file
found way too much fuel and boost was being added and many of the limiters that hold back power where missed
Also the ecu had been opened and the casing was bent which we straitened

We put the ecu back to standard and the car made 249bhp with just over 400ft of torque (blue line)

After out remap the car made 324bhp with just over 500ft (extra 75bhp plus 100ft of torque red line) this was using 1/2 the amount of fuel and less boost that the other tuners remap

We also set the egr to closed all the time and the way we do it the engine will still regen

We also found that this was not the original ecu for the car and had been changed at so point with a second hand ecu so we corrected the cars data in the ecu as well
