Fuel pump fitting question

[gmogle]

Hi guys,

Got my Supra fuel pump ready to fit.

But can I fit it in place of the existing pump or will it need to be fitted then mapped straight away ?

I am keeping the standard FPR and have 4*850 injectors.

Is this gonna be ok to fit without having it mapped straight away ?

[J.j.]

have you had it mapped with the injectors? fuel pump alone will not require mapping straight away, you'll just ended up running a little bit rich i think.

Injectors will only inject what they are told, pump wont make that much difference.

It will run a touch rich.

It will run a touch rich.

Scott, you have seen my car run and the dyno printout, will this be a bad thing ?
