"If" You need a full live map then £500. If not, then it may b substantially cheaper. EG: Most cars up to 400bhp are absoluely fine with just a chip to suit your spec. our 350bhp P8 chip to peak at 2bar and hold 23psi on 803 is £150.

Closed loop is included in those prices if you still on P8 as all our P8 calibrations have it as standard.

Wasted spark with ecu wasted spark driver is £550 fitted.
Only £400 fitted if you dont use a driver and just switch it on in the P8, but then you may have to use aftermarket tach, but we have a good solution to try first that normaly works.
