SD or 6.0 TT chip

[86WH1turbo]

Looking to upgrade to one of these. Will be using powerlogger and WB correction along with EGT. Which chip works best and why? Any help would be appreciated. Thanks

If it's mostly a street car, then I would keep the MAF (6.0 chip). You can make speed density (SD) run well, but it requires more tuning from the user. So, it's basically a personal preference.

I'd like to add that you could start out with the 6.0. Watch your logs and wideband readings during different driving situations this will help you in tuning a SD when you make the switch. I am happy with the 6.0 and will be for a while. Drivability is great and the correction a sweet feature.
