I have a gauge for that

You need to be careful and follow whatever you have set for the PE enable (< pe enable is cruise). In the WOT cells, keep it at 1.0 so you can accurately adjust the VE table. If its not 1.0 then the PE multipler and the OL multipler combine, so if its 1.10 and your PE ratio is 1.15, then your ratio is going to be 11.62 (14.7/1.1*1.15), which is too rich.

If you are running N/A and the MAF is not maxed out,running SD will not give you more performance,granted that is if the MAF table is scaled CORRECT using a wideband!!
Do not rely on your narrowbands to dial in your A/F (air fuel),if you want it done correct and accurate get a wideband.
Read the stickies on the hptuners forum and you will get the hang of it

The reason i went to SD was because i was having backfires when i would spray using the MAF. My MAF had never been scaled though. I also heard that for big nitrous shots it's better to run OLSD to eliminate the risk of O2 or MAF malfunctions which may cause major problems. I want to try CLSD so that i can run stoich and my STFT.
