Problem is that 2Black was ordering one over a month ago from BTR and was going to dyno it. Hasn't been back on line since to my knowledge. Also BTR told me they had sorry results of only 6-15 hp gain and then some @ 25 hp gains reported. Not too reliable, but did offer a full refund if not satisfied. I wanted to find some one that actually has their own test results, not the BTR results. If it is only a few HP gains then it was no better than what LAP found when they put theirs on my '13 and dyno'd it. Only decent thing was a smooth out of the air/fuel ratios near top end, but definitely not worth the money. LAP agreed. The dyno also showed that only 4-5 hp gains with K & Ns, but no better than with a new clean filter. Almost same without any filter. 4-5 hp is unnoticable by seat of pants and timing unless you count extra noise as something.
