Re: Custom tunes on 5.3

Hello from Germany ☺️

I recently bought a 2008 Chevy Suburban 5.3 FlexFuel.

Next week, it's getting an AFM delete and a TSP Chopacabra camshaft.

It already has a Magnaflow exhaust system and a 4" intake with an open air filter.

I also ordered a Diablo i3 Tuner

Can anyone help me with the tune ...
