spark plug and gap?

[Crawl]

A few days after buying my DSM, being a DSM noob I ordered BPR7ES plugs and was told they were pre-gapped. based on my mods (not alot) shoudl i be running the BPR6ES instead, and what gap size should i bet at

Under Drive Pulley
Intake Cone, Intake Tube from MAS to turbo
2.5" Turbo back Buschur exhaust w/ high flow cat
(have gauges and manual boost controller, running at stock boost for now)

thanks in advance

Any old search reveals the answer is .028". Don't believe the pre-gapped nonsense. I bought a set the other day that were gapped perfectly, but I've also had sets of the exact same plugs that were way out of spec before.

Hey, yeah I dindt believe it either, i gapped them to .028 as stated, i have searched, I jsut wasnt sure if the gapping was different between using the 6ES and 7ES's, my main question is which of the 2 should I be using?
