Took my car to BTEC Racing in Shipton Under Wychwood today as I had no idea what the engine figures were. I knew that GBS have a specific map to get the car through IVA and I assumed that this was what I still had installed.
I have a 2.0 Zetec fitted with the GBS plenum chamber. The results are:
Max power - wheels 127.3 bhp @ 6182 rpm
Max power - engine 167.7 bhp @ 6182 rpm
Max torque - 146.4 lbft @ 5319 rpm
Got to say that I am very happy with that result from a standard engine.
