well The audi has recently been graced with some new silicon yielding a not so insignificant 30 bhp and 25% torque gain. Whats the best next step to aim for.
For those not in the know its a VAG 1.9TDI pre PD standard output 110 bhp.
obviously i'm quite happy with the smidgen under 140 bhp that she has just now but i'm not sure what to target next.
Some say bigger injectors some say a hybrid turbo whilst others say headwork.
It isnt an RS Turbo or a LET so i'm pretty much stumped.
I was thinking along the lines of a quick port/polish getting the elbow off the turbo and removing the restrictions there and a replacement intercooler.
but c'mon guys floors open ridicule mock or advise as appropriate
