This car was built completely by Kirstyn. She installed the motor entirely on her own. After this was running perfectly, it was completely tuned and dynoed. The thing to realize here are the gains in the upper RPMs. 10WHP was gained by nothing but tuning over a stock LS map. The map was also street tuned and a increase from 29MPG to 37MPG was realized. The overall feel of the vehicle is significantly improved. This is a perfect example of what a proper tune can do for even a stock motor. The stock ECU is tuned very conservatively.
