you cant run much more, and i advise anyone doing so to have a full load fuelling check, as the turbocharger will outflow the little 803s at high rpm which is why we advise the use of 55s on the T34.
Ok, im asking because currently I have stock fuel pump and green injectors in the car. Im currently running 19 psi boost on T3 and im gonna order a new chip from you at some point as anyway im in need of lambda control (and some extra power...

). You also seem to sell chips for T3 which run 25 psi, so its either one of them for me when I buy new chip...
