Kleeman K-Box or RaceChip?
Has anyone tried either the Kleeman K-box or the Racechip GTS Black? I want to tune, but being a new car scared to death of any warranty issue, these seem to solve that problem. Please let me know your thoughts or experience with either of these products!

totally wrong area. Piggy backs suck. They lie to sensor inputs to trick the ecu into doing things. Think about your life and how well telling lies has worked out.
Simple example..... tricking the ecu to run more boost because it doesn't think it's hitting the factory target setting. Now it runs more boost but with too much timing, engine may knock now it pulls timing. defeats the purpose. Or better yet the ecu sends the transmission the predicted torque amount. stock 500tq.... now running more boost 600tq, however the ecu is being lied to. crap in crap out. Ecu does not know it's making 600 torque now so the transmission doesn't shift as hard or use correct amount of pressure to compensate. Get a real tune. A reputable shop will not cause issues.
