Drivetrain Battle/DNA Tune Thread
Similar numbers to the BMS plug in. Depends on conditions too. Sorry it won't upload on my phone so I can't see the pics of your dyno.

That seems good to me. Assuming 15% drivetrain loss that's 240ish crank, around 70 over stock. BT claims to hit 45-55 over stock with stage 2. I'm shooting for 210whp with my Stage 3...

Has anyone noticed a change in the sound of their exhaust after a tune?
I have been playing with an alta 3" turbo back catless. I have been trying to get a sound I like.
At the moment I am close. I Installed a vibrant performance 18" resonator this weekend and it made the exhaust very quiet. I was shocked. I was trying to shift a drone to a different rpm range. It helped that a bit, but I was a bit surprised how much quieter it is now.
I am just wondering what the stage 3 tune will do if anything to the sound.
I am hoping to get a bit more sound but not much.
Thanks, Nate

And so begins the task of trying to pass inspection. I'm thinking, revert back to the stock map because I HIGHLY doubt I'll pass with the Stage 2 tune uploaded, install the O2 spacer, drive around for a bit and pray for the best. Hopefully, that'll do it. If not, throw the stock dp back on (which I really don't want to do) and try again.

I was under the impression Battle can remove any reference to emissions faults / CELs in the ECU, no?

Can't help but think about how slow my car is going to feel for that (hopefully) short period of time. Makes me sad

Don't worry DTH2CHRM, I am in the same boat as you being that I'm in Cali. Although I may have a found a solution to my troubles...

So for those of us in emissions states, we're kinda screwed when it comes to running an aftermarket DP.

Now they changed it so year 2000+ cars don't need the dyno, but all monitors must run now so I will still fail.
However that is kind of the point of the test, if you passed with an aftermarket DP then the test is kind of useless...

Yeah that'll be my option if plan A doesn't work. I REALLY don't feel like dealing with the dp swap. Lol

So you passes smog after installing the stock DP after driving around for a day? The Cel will still be there record, mm.

You will pass, just clear DTC's so it clears memory, make sure you're on a stock tune, and drive it around a bit so the monitors run. Should pass easy.
After you go through the drive cycle it clear itself from being a permanent code.

Do you happen to know how deep the testing is in Texas? I know the inspection is a bit stricter up in the DFW area then it is down here in Austin, but I'm just wondering if maybe I can get lucky and run a catless DP with Battle's tune and still pass the emissions test.

Easiest plan is to switch back to the stock downpipe on the day you get your emissions test. That's what I'm going to do, luckily I still have 1.5 yrs left.
No way you can pass a sniffer test with a catless DP, the exhaust is noticeably different without the cat... I can smell it at most stop lights...
