Pontiac Sunfire GXP Concept 2002

Posted by on April 6, 2012

Pontiac Sunfire GXP Concept 2002I have seriously wanted to do this car since the day I got. It was not in the most demand and no one else had a tune for it so it would be perfect for me to do. I finally decided I would tune it. The car is pretty good to start, but just like most cars that start good you can tune them into being literally perfect. I have never loved and hated so much before tho. It's so amazing that it blows your mind and yet occasionally there will be not even a mistake, but just a slightly less than perfect turn that will be so annoying. If you have this car I highly suggest using this tune because it really is fun to drive. 

I liked the old model styling better than this one, but I guess this GXP version was changed a bit because it looks cooler than the released model. If Pontiac made cars that looked like this and more importantly performed like this they would definitely still be in business today.

P.S. this is the first tune that has been done in both mph and kph
