I have now fitted both the Airtech intercooler and the Autospecialists CAIS and I can really tell the difference. Not so much in the lower down rev range as the intercooler and induction system work best at high boost levels but the turbo is much stronger now up through the revs. I seriously think both together have added possibly 30 bhp which is pretty good for 500 quid. It seems so much smoother and effortless too.

Has anyone got a simular spec'd ST to compare bhp figures.

Mine has de-cat, dsci remap, autospecialists Gen 2 CAIS, Airtech Gen 3 Intercooler, dual piston dump valve.

Here are a few pics
