50 wet shot will be fine, 50 dry shot you should ask your tuner, it really depends on well dialed in your fuel trims are right now. If they aren't within +/- 1-2% than you may throw some lean codes from a dry shot.
Great guys! I asked Lund and they say I indeed need a tune revision.
Thanks for your help as always!!
That should not be needed, the car has 2 factory widebands and the PIDs are supported by HPT and SCT. Also a single wideband would not work because there are 2 banks, you would have to have it attached at the X pipe which requires permanent modification.
You sure about they told you that you would need an additional wideband? How do they know your friend even has a AEM wideband?
