Jannetty Racing should be avoided at all costs! I brought my 2014 chevy camaro in to have a dyno tune, a new downpipe (free flow) and cold air inductions box installed. The car was left off on a Monday and promised back Tues afternoon. The car was not ready til Friday. When I picked the car up at Jannetty Racing Waterbury CT on Friday everything seemed ok. Ill admit the cold air inductions install and new down pipe was done right but the dyno tune was waaaaaaaaaaaaaaaaaay off.

When I had someone else dyno tune it later they told me the air fuel ratios were way off and the ignition timing was so far off it could have done damage to my engine. You can see what to do if Jannetty Racing of Waterbury rips you off at jannettyracingscamripoff.weebly.com

Another thing - I found out later that Jannetty Racing of Waterbury is way too expensive compared to others. If you need a dyno tune go to J&M Motorsports of Manchester CT.
