Have any of you that have tweaked the Turbo and/or fuel pump run any tests to see what performance improvements you have gained ?
I was thinking of either a 0-60 check or a rolling road BHP check ?
I have tested my ZX TD with a stopwatch at 10.27 for 0-60 which is slightly faster than the book speed of 10.5. Mine is still standard at the moment and is probably due for a air filter change.
