Dan's RST now has my old Charge cooler and tonys old chipped ECU and has had the same set-up @ P.E and he made just over the 200 bhp mark and feels the same strength pulling as mine and tonys did

Interesting tho i havent been back on the rollers since the GRS was fitted, but i would place a bet that its down on power on the rollers compaired to the Charge Cooler
