Want more power??

[GMC4Zee]

The 6.6 L8T has been out for over 3 years now and aside from cold air intakes, exhaust or pedal commanders there is no aftermarket to up the horsepower. Now I am not talking turbo or supercharger but maybe better intake, larger throttle body, cam or programer. GM really locked this one up. Its frustrating for us people wanting to add just a little on a budget. Am I wrong or is there more out there than I think? I also would of expected with the 10 speed trans a bump in engine output. Get us to 450hp and 500tq please.

HP Tuners just announced access for tuning on these.  Requires ECM swapping or modifying your existing one.

10 speed comes down to making much better use of the power the L8T already makes via more gearing ratios.

Someone posted a supercharger is no available I think Magnuson.

A camshaft swap with a really good tune would do wonders. However does the tuning really needs to understand these controllers though.
