I know many other have chipboxed their Spiders. I finally got mine installed this morning and all I can say is WOW! In sport mode the Abarth is a beast. So much better than stock. Can't imagine what a complete flash tune is like. The install took about 1 hour and I was using the lift at my buddies repair shop. Thank you to Driving Impressions tech support for quickly answering the phone and giving guidance. With the guidance from Team DI getting at PREX1 was very doable from under the car. I would recommend that approach where it is possible. Now the car is parked back in my very small garage, most likely until spring. I will next install the Pedal Booster come springtime. Living in the NE USA can be a drag at times but at least my local skiing resort opens this weekend. Yea!
