I recently had my 150bhp sri remapped to 176bhp. I was told this was all i could really expect as it has 94000miles on the clock and pushing it any further would only be asking for problems.

Now i had a tuning box in previously and although, granted the remap has smoothed out the acceleration i see very little difference between the two if any.

Is there a feasible stage 2 remap out there and what are the kind of costs associated with it? I presume its a bit more physical work then just the remap??
