Currently teeing up an A.R.E Intercooler from a bloke fingers crossed.

2000 to 4000 is within the main operating range of a td42. The only time you should be under 2k is when you accelerate from a stand still. Or maybe coasting along at 60 in 4th.

By the sounds of it you may not get the increase you are expecting due to other factors with a turbo change. If it cant easily exceed 3000rpm then you may have a fuel supply problem, be it the ip is worn out or possibly a restriction somewhere.

Who is this so called tuner?

As for the turbos either the mamba or kinu will suffice. Both are china built items so trying to compare the 2 in quality is not really measurable. I would be looking at something like the 18 6/8 combo.
