arp head studs come factory installed?
regardless of the #'s there are always going to be people who question the credibility of a tune/setup/numbers given. it is part of the inherent nature of having your own opinion. personally i don’t believe anything i read and only half of what i see on the interweb these days. i’m sure there is a lot of good tuning involved with this setup, but allowing some e-mechanics to turn a thread into a pissing match with a professional shop raises eyebrows, not customer confidence… but that’s just my opinion.
