Spark Plug Gap Opinions
i went to the local Oreilly's and got me a new set of Motorsport Platinum's to change out this last weekend and they recommended to gap at .54 thousand's. I immediatley thought to myself "man thats a huge gap!" So I called a budy of mine up thats used to work at ford and he builds alot of the local guy's mustangs around town (not mine though, I just ask advice here and there) and he said no no no! gap it at 44 not 54. so I gapped em at 44 and it ran superb! I just wanted to know a few peoples opinion

On very high compression and f/i engines it is common to use plain ol' tungsten electrode plugs, gapped to 0.035" or so, to get a fat spark less prone to "blowout"--and needing to be replaced every 18k to 25k miles.
However on a n/a, OEM compression engine, platinum plugs at 0.054" will work fine for 75k+ miles.

A lot of people still gap .035 that run blowers - Personally I agree with your friend - I've been gapping mine at .044 - running 8 pounds of boost through my engine and never have any problems - I'm using a plasma booster as well so that should have an affect on it.
But I agree with whats been posted - use the what the factory says for a factory motor - once you start getting in to custom builds, ported heads, blowers etc.... then you might wanna change stuff up .... but until then trust the factory specs
