i was running greens, 3 bar map sensor, standard turbo on a stage 3 collins chip at about 16 psi i think on a standard headgasket ..
mark shead set the fuelling up ran very well

now running 24 psi on standard headgasket and a t34 .63 exhaust housing

044 fuel pump being fitted soon and will be turned upto 26 - 28 psi on a standard headgasket


it might all end in tears .. it might not only reason i changed the standard turbo was the wastegate stuck shut and a vane fell off

and the greys get fitted next year too
