If you are gonna drop $300 on tunning, just spend that on your own set-up.

Dynotuning is relable. Not gonna half *** this project.

I don't understand what you mean?

Chris Harris

Street tuning is more accurate as far as A/F ratios go...you cant properly replicate the airflow the IC and rad sees while on the street or the ambient temps.

The only thing dynos are useful for are safety, steady state (ignition timing tuning) and power readings (well, thats not really ALL, but for this discussion it is)

We'll I'm sure I would be ok with street tuning but since I have the cash why not do it right? If both were free, would you still pick street tuning Chris?

Chris Harris

If it were free...I'd street tune first, get good AFRs with a solid timing basemap. Then hop on a dyno and tune in the timing maps and change the fuel maps as they change (because of timing changes)

When the tune was solid on the dyno...I would take it back out on the street and nit-pick any points that show up on the street in the fuel maps that didnt show up on the dyno.

Street tuning is reliable. Use the $300 that you would spend on the dyno and get yourself a wideband O2. Listen to what xenocron said and you may only need an hour on the dyno to make some timing adjustments after you have street tuned a good basemap. Plus you will be happy that you did it yourself and gained some valuable experience. Good luck

Thanks guys, guess I have allot of reading to do...LOL
