Who’s tune did you go with?
i like it, but...if you want LOUD, the MF is not for you. it's a bit louder and more of a rumble than stock, but not much. if the stock exhaust is a 1 on a scale of 1-10, the MF catback is about a 2.5. imo, this is what the stock exhaust should have sounded like. there are times i'd like a bit more volume out of it (like a 3.5-4), but if you are looking for a stock-ish, not obnoxious increase in volume, the MF will do that.
not sure what their website says, but when i spoke with them they anticipated i'd see hp/tq gains of 50+ which is about what I got (a bit more actually). i asked about the canned tune, which i personally wasn't comfortable doing, and was told that typical gains from the canned tune are definitely less than the dyno tune for fairly obvious reasons.

i just looked at their site.
the dyno graphs they show for the canned and dyno tunes are the same. just guessing here, but i'm assuming the hp numbers being a bit higher than mine and the tq numbers being a lot higher are based on whatever mods the vehicle they used had and that they probably pushed that car to the extreme to get those numbers. i wanted something safe and stock-like without going too crazy. i got what i was promised +56hp/+67tq and i'm happy with it. plus i know it's rock solid and backed by a very reputable shop.i just looked at their site.

I think adding the secondary cat deletes would give you that 3.5/4 you’re looking for.
@DaBears4Lyfe is the BTR and Alpha Speed tune expert and may be able to comment.I’m glad you’re happy. And my questions aren’t directed towards you since I know you’re not likely to be able to address the inquiries.
I’m still interested in how they arrive to those numbers. BTR had an in-house tuner, whose contract expired. For quite some time they weren’t offering any tunes because they lost their tuner. They then partnered with AlphaSpeed and that’s who’s doing their tuning now.
Some other members have dealt with them before.
New canned tune option from BTR
BTR posted a tune progress update earlier; 469/484 for FBO and E30..... I wonder what the difference in power is for that e30 vs. the 91 most Cali people would be using....that would be helpful for comparison across other tuners who are tuning to 91/93....
