Just got back from RS Tuning.Good news my ECU dumped and is mappable,apparantley mine has the GEN2 ecu fitted.
Paul put the car on the rollers to see what it was doing,it gave 280bhp at the fly which is down on the official figure Nissan quote.He seems to think that there are gains to be had from mapping,i am going to get the lower plenum from Sunset then have it mapped.Hopefully get to 300bhp,but its a better torque curve i am after.
