Tuning in Northern IL

I've got an 05 Avy with a 5.3L and all that has been done to it performance wise has been a cat back Flowmaster exhaust that is pretty mild.  I want some more horses but I'm not sure of what to do next except maybe a good tuning. Does anyone know of a good shop or someone that would put a tune on it that is in the Northwest Suburbs of Chicago or near Rockford? I'm in Huntley which is about halfway between Schaumburg and Rockford basically.

I took a 2-day tuning training class that an outfit does in different locations around the country that they gave in a shop in one of the northwest Chicago suburbs.  Was a real nice facility.  At the time their dyno was the type that you removed your wheels and bolted on they dyno's brake units to the lugs directly.  Looked like their largest clientele was ricers including numerous all-wheel drive Subarus, but I imagine they'd be happy to take your money to do your truck if they've done a few in the past.  I'll have to see if I can look up where that was for you.

I was at GRDTuning which at the time was in Villa Park, IL, but looks to have moved last year to a West Chicago address.  From their facebook page, it looks like they specialize in German and Japanese cars however.  You can give them a call and see if they can recommend another tuner if your truck isn't in their repertoire.
