If you are maxing out the MAF at wot, then the T+ won't help much without the Extender. It adjusts fuel by modifying the MAF values, so it can't add any fuel once it reaches 255.
You could use fpr to adjust wot and then the T+ for base fuel and get blms back in line if your chip is too far out of wack. Otherwise you might as well adjust fpr to tweak wot and let the chip (blms) take care of the rest. I could be wrong, but I think that the chip makers spec a fpr setting as a starting point and slight tweaking is perfectly acceptable.
Not that there isn't something to be said for using the T/T+ for the modern maf benefits alone.

Ah okay, so if i.e. you adjust the WOT setting on the MAF-T leaner it would raise the MAF #s? I dont have an issue with pegging 255. For some reason I have never seen 255 hit before. I believe I made it to 251, dont remember for sure, but its usually in the 240's. Dont know if it has to do with something else I have on the engine (like maybe the Tlink boost harness) but I remember posts in the past of others wondering why there car does the same. Maybe its just tuning. Anyway, if this is the case that the MAF #s would raise up by adjusting the translator then would there be a benefit for me to do so to get the MAF #s as close to 255 @ WOT as possible?
By the way I have the regular MAF Translator, not the Trans+. Thanks.

Leaner will lower the numbers, faking out the ecm to think there is less air thus reducing fuel.
There is no advantage to having the maf numbers at 255. At 255 it is no longer possible to pass the true mass air flow to the ecm. Kind of like pegging the digital dash at 85, if it is blinking 85 you have no idea of the true speed.
That is where the Extender comes into play. The maf numbers are 1/2 of the true numbers (thanks to the T/T+ and LT1/LS1 maf's ability to measure more than 255) and the chip compensates.
It is not uncommon for stock mafs not reach 255 because they are faulty, not because there isn't 255 gm/s of mass air flow.
