Default Will FRA mod and TB by-pass mod wreck tune?

I currently have a dyno tune on my car, I am debating doing the TB by-pass modn as well as the free ram air mod. Will this cause any lean or rich conditions?

And are they even worth it?

Thx

I think FRA might effect AFR, the FRA is a good free mod, just check the AFR after the mod. The TB bypass should not effect your tune.

FRA is the every little bit helps mod. But messing up a tune, no way. Its good for like .05 in the 1/4 max.

Edit: My bad, I'll remove the quote part to remove the confusion.

I didn't say it will mess up the tune (Tune is more than just AFR), I said it might affect AFR, which FRA did little with my LS1 SS. It may or it may not, that is why I suggested that recheck the AFR after the FRA mod.

He didn't say that you said that it would. It was in response to the poster, read the title.

I live in the north and havent had any problems at all since I did the TB bypass 6 months ago. I agree it does not do anything performance wise but it sure makes it a hell of a lot easier taking the TB off.
