5.3 w/standalone and th400

[Bajakguy2]

Hey,

Iv been on a mission searching for a clear answer in which OS is best recommended to use for a 5.3 with a stand alone harness (From PSI Conversions) And a TH400 trans. This is going in my race truck and wont have to worry about any emissions or what not. Thanks for the help!

How are the O2 heaters setup in the PSI harness? What O2 connectors? What are you racing in, series?

[Bajakguy2]

1400 series, its Baja trucks. Let me send post up some photos of the harness and you can check it out. my buddy ran it in his race truck with his ls1 and then ls7.

My personal preference for DBC OS is 12212156. Plenty of car and truck tunes available and all the custom OS's are there.

Personally I'd ditch the MAF and run SD. I tune a lot of Ultra 4 and BITD/Score....... Too much relies on a MAF when its there and the conditions you will see tend to destroy them rather quick.
