Longtubes going on today...tuning question

[Zelek]

Not a joke. I'm not looking for your advice on how to build my car, I'm looking for you to backup what you have publicly presented as fact because your lack of understanding of fuel trims, etc has shown in previous posts. Perhaps you have some factual information to back up your claims. I'm here to learn, but your statements go against things I have been taught by respectable tuners in the industry.

You obviously have done little research at all on this subject. Like I said, go ahead and keep running your stock tune with headers. Enjoy your day.

Didn't realize you were a top tuner for the Coyote platform.

No I'm not. How about you ? Or do you just parrot everything ?

And yet you still can't answer any of the questions.... Aside from my personal education on the subject, I have seen multiple screenshots of conversations with Lund asking for a retune for long tubes and Lund replying that it was not necessary. Are suggesting that Lund lies to customers to avoid additional work?

I've seen enough of your posts to not believe a damn thing you say.

The tune already factors in the logic for it. Like I said, you have done no research.

That's not how this works

Right on. Keep on keeping on.

Anyway, by your logic you need a tune to go with a 3" catback as well.

Do you need a tune: No. would it add 'slightly' more power: probably. but for NA it has to be one of the worst HP per dollar upgrades. will help more if you go FI, but then it sounds like aftermarket cats like to melt with boost eventually. Probably sounds mean though.

Nonsense ? LOL. For simplicity sake, the front wideband o2 monitor A/F ratio, rear o2 cat efficiency. Dude has aftermarket cats. Hes gonna get p0420/p0430 anyways, all this happens AFTER the MAF. All the MAF sees is slightly more airflow and compensates. All GOOD tuners do is move the exhaust cam around and mess with the timing a little for a little more zip. So you can run a stock tune with headers no problem.

100% accurate. These guys forget we run closed loop fueling and commanded lambda is always targeted. STFT’s can compensate up to 10-15% safely to keep targeted lambda.

The guys saying you need a tune revision for long tubes are the ones who pay to retune their cars if they change air filter, radio station, and add a rear seat delete too……….

It won’t add ANY power because nothing will change unless they increase spark advance. Which they do with stock exhaust as well……. This is the benefit of the Copperhead ECU with the MAF working with closed loop fueling targets….

I have LTH headers. I ran the car 1 or 2 days w/o the revision. After the revision, the car runs better. The way I see it is why not let the tuner do a revision and make sure everything is working great? Are they worth it? Abso-f@cking-lutely. My car runs and sounds amazing with them and the AWE catback.

Careful now, you'll upset the know-it-alls.

I put long tubes on my 17 back in Feb of 18. I drove it for 4 months until my appointment to get it tuned, nothing adverse happened to my car.

Placebo. You can also see yourself that it’s looking great in the logs before hand.

And where's your insight ? Your just repeating what you hear from some tooners.

Exactly.
