It's a low pressure warning on the fuel system - probably the fuel pump body is becoming worn. Chat to Doug about it

Just out of interest, do you mean the high pressure pumps?

Yes - the high pressure pumps. MRC will almost certainly have put in uprated Autolec pump internals, but after a while the bodies start to go I believe, and then you can get low pressure under high flow conditions, especially (in my case) on bank 2.

As a matter of interest, did the light come on immediately after a fairly sustained (ie 3-4 secs) at full throttle??

I spoke to MRC it’s not had any pumps it’s only a stage one tune just had NGK racing plugs. It was mapped nearly three years ago now. Mainly when it’s cold then once warm doesn’t do it as yet. Car runs fine goes like a rocket. It’s had cold start delete when MRC mapped it that’s on the invoice.

OK - doesn't sound exactly like mine then... But there will be a code stored somewhere - probably best to let them have a look
