zvhrst i think it was you as the guy i emailed is runing fuel pressure mod only, that lambda sensor idea is good apparently one that is half decent and gives acuret reading will cost allot thoe can anyone recomend me a cheep gauge and sensor that will actually work and not give dodgy readings?

I have an xr2 with escort rst lump will there be a mouting for it or will i have to get my downpipe modded?

Also if i am getting one welded in where do i want it back box or downpipe?

I was thinkning back box would be allot easier plus i could take it out and maybe use the tappd whole for another device
