OFT on stock
 

Good day, guys! Sorry, just a newbie on this one. I was wondering if this is going to be a worth buy or if there’s any or even a little noticeable gain being used on a stock 17 brz, just with a catback exhaust. TIA!

I dynoed my 2017 before and after stage 1 complete stock: http://www.ft86club.com/forums/showthread.php?p=2963580

Not worth unless you plan to get headers eventually except for maybe the redline if you do autocross

Its worth it if you want to run E85 otherwise wait for headers like said above.

Thanks guys! Probably will save first to get new headers

My experience with the Stage 1 tune, 3.02, was good on my stock 2017 86. Throttle response is better and it doesn't hang between shifts like the stock tune does occasionally. Does it change it into a rocket ship? No but I think there are more benefits than the numbers on the dyno suggest.

I think the best part of OFT is the ability to run E85 on an otherwise stock car - best bang for buck when it comes to a horsepower increase.

Yeah, this is also what I noticed. It hangs between shifts

IMHO if you are going to upgrade to stage 2 later, get the OFT as soon as you see a deal on one used. Stage 1 doesn't give you much, but it''l give you a little and you'll have the tablet for when you upgrade. It's definitely worth it for stage 2- big gains.

If you are never going to upgrade to catless, don't bother with the OFT. Stage 2 is for catless. Stage 1 is for catted. Stage 1 alone isn't worth an OFT.

Thanks!

I remember when I called Shiv regarding the 2017 tune he said stage 2 would be fine for catted header. I think this was version 2. Car runs smooth for me.
