A/F's----survey
With all the talk about air fuel ratios I thought it would be interesting to see how many guys/girls that have put chips in there vehicles had them dyno tested or wideband for A'F's.. Just a yes or no will do...

Hmmmmm......
I will say my 2 cents on this, hehe. Any of you guys who actually do the pulley, chip, filter, etc. and don't go to a dyno to check the tune/AF ratio are playing russian roulette with your truck! I know there are some good tuners here but you can only do so much via mail order and there are MANY variables with any one persons truck. yes, its kind of expensive and yes its kind of a pain but it should be done or all you are doing is guessing...period. the dyno is an EXCELLENT tuning aid. And make sure you find one that uses a wide band O2 set up and not the sensor up the tail pipe. They are not as accurate and tend to read leaner than an O2 set up.
