04 run lean with gotts mod?
Have read conflicting info on whether the gotts mod will cause an 04 5.4 3v to run lean. Seems to be non issue on newer models but read 04-05 are different. Any one have definite answer one way or the other?

Gotts mod will not affect the air fuel ratio for any year/model. It is upstream of, and doesn't alter the location of any/all sensors. Intake mod lean issues are [usually] caused by changing/altering the MAF location.

I agree 
The Maf is going to tell the PCM how much air is being fed to the engine which will control FI pulse for the correct mixture, and the O2s will give feedback based on the information they gather, to keep everything at Stoich.
WOT would be the only area where they would be ANY concern, but that mod doesnt allow enough change in air flow to change WOT AF signifigantly.
