Giac sells the best ecu upgrade! *imo*
My local dealer here in Hawaii is trying to charge me $3200 + $120 labor... They told me it cost $3200 because GIAC sets the price not them. Is that true or are they just trying to rip me off?
No, that is correct and that is actually a discounted price. The software previously retailed for $4100 and only went lower during our group buy special.

Drive up to GIAC and have them do it right there.
Thanks, Tom! I'm going to do it next week.
IMO It's great value for the $$$. Performance gains are significant.
Tune + Exhaust will definitely keep you smiling! Make sure your plugs are good and check your intake filters. Surprising for me how quickly the intake filters require maintenance cleaning. May want to check your hoses as well between intake and inter cooler. Considerable heat under the hood softens the hoses. If the hose is not rigid and easily collapses may want to change them.

Thanks for the recommendation!

Tom,you got that right!
I picked up my GTC from TAG this evening I can't believe what an improvement the ECU upgrade made on the overall throttle response and power. I couldn't be happier with the results.

Glad you're happy with it! It's a bit shocking how these lux-o-beasts transform, considering they're quite powerful already.
Nothing to release yet. We're working on getting some ECU reads at the moment. Once we have all we need, it shouldn't be long from there.
Very hard to explain in detail the seat of the pants change in driving experience. Good to know you are able to experience the smiles first hand.
met one of your reps at Cars and Coffee in Irvine.
