Handheld Tuner

[wlg101190]

I have a mail in tune from Amazon, which as I read about them, I learned they send pretty safe tunes. I was wondering with my tuner, if it would be safe to up the WOT A/F ratio a little bit, since I sense it running on the rich side. Will I notice any performance difference?

You sense,or you know via a w/b?

Mystic03 got his Amazon tune and I believe he said it was running rich according to his W/B as well and was going to pull fuel

Unless you know the AFR don't touch it, and if you don't know the AFR stop driving the car until you find out. Even a good tuner like Amazon can make mistakes. I've had email tunes that were spot on, some that were real rich, and some there were lean as hell.
