I have a 2002 Maxima and im just finishing installing full Cattman Exhaust on it. I feel like its time to Dyno it so I can start watching the Air/Fuel mix. When I go get my car Dyno'd are there any specific things I should do or check while there... other than get a Video Clip(got that covered).

Thanks for any advice.

 

A video clip is for 'bling' IMO. It's the data that counts.

If you're going to a dynojet, this might help:

It would have been better if did a dyno before but you might be able to use older 2002 dyno results. The place who did my dyno testing emailed me PDFs of the results. If you send me email I will send you my results but understand that they were from a couple of years ago (I have both stock and with an intake). The only other pieces of advice not noted in the dynojet thread from above is that you must make sure your front tires are in very good condition and your engine should be warm. Good luck.

 

i'd only worry about a/f ratios after you do the headers. but dynos are good to track performance and to compare it to others who have done the same or similiar mods.

 

you should buy and install either a apexi safc-II or vafc-II so then you can tune the a/f after you dyno.

 

you should do one one with your injen on and one run with your stock airbox or a short ram on,

or just remove the injen all together . . . .
