Here is the previous ultra lean timing pulling tune from another flash tuner

vs. my tune with boost adjustment and much richer and more steady timing

Some days this business can be a nightmare of answering phone messages and other tedious stuff I hate - and other days this business is the most fun you can have in this world

I love tuning cars and working on the dyno

 

nice

 

The thing with adding fuel and making more power does run counter to common conceptions - and in reality running richer does - IN AND OF ITSELF - generally lead to cooler egts and less power

However - the in the case of stock ecu flashing, when you can hold the ignition timing by keeping the ecu's happy knock ears from hearing knock activity you make more power.

The xtra fuel is mostly a anti knock aide which helps maintain your ignition timing

In the case of a true stand alone ecu - you would make more actual power running leaner

The inner workings of the stock ecu take lots of careful testing and watching to unravel

The end result is a lower egt, less knock and more power along with a smoother feel

I would trade a slight loss in fuel ecomony for rock solid reliability anyday
