Default Speed Density Tuning

Can anyone enlighten me on this?

Plus, my MAP is at 57-58 and I am getting feedback that this can be an issue too.

My car is a 2000 A4 and I am running a 232/236 .575/.578 LSA 113 +2, and I heard that tuning A4 with lobe separation let this one can be a PITA.

Thanks,

Micah

Man, this stuff is interesting. I also have to be honest, some of it is going right over my head.

Shouldn't be a problem. Check out the SD tuning link in my sig for an idea what's involved.

Tuning is pretty simple once you understand how the PCM works and what tables do what. The actual tuning just takes a lot of time and trial and error.

Nope, not a problem. Try having 70-75kpa at idle. Based on your previous experiences, you might be able to do a better job. However, Learning on a stock car would be better. With your car, SD or SD/MAF will work well when tuned properly, either way.
