I have looked around on the forums for about an hour now and cant seem to find out if the AFE Scorcher will cancel the code thrown by installing a DP. Anyone have experience running the Scorcher with a DP?

No it will not clear codes, the only code clearing, non-flash tune, is the JB Stage 2 tune. This is the same for RaceChip, AA8, Dinan and the AFE Scorcher you are looking at. Get a catted hi-flow and call it a day, you'll maybe sacrifice 5 hp, but no codes for me with that setup with RaceChip and now AA8. Otherwise if going catless you have 1 option.

Thanks for the Information, just go catted = Problem solved. I really enjoy the Scorcher. I'm not killing my car trying to hit JB4 ,map 7, super aggressive.

my understanding is catted + any piggyback OR non-catted with JB4 map1-2 is the same thing, no?

I did Fabspeed and I have had no CEL issues, not all catted are created equal, and this was slightly more $ than some of the competition, but 2 months in and no issues and significant gain/throttle response improvement when paired with stage 1 tune.

AFE is a stage 1 tune, it does not cancel the CEL.
Getting a catted DP does not guarantee that you will not be getting a code. I have seen all catted DP fail, that being said if you get a good brand ( Fabspeed or Evolution Racewerks) you have a much higher chance of not getting any code.

For max power and sound get catless DP with a Jb4 or get catless DP + Afe scorcher and add the BMS can flap module to clear the code.

Thanks mike! Will the BMS can flap modular keep the code off or will I just have to reset it every 70 miles or so?

You will need to delete the code every time.

I'd recommend going with JB4 out of the gate to avoid the CEL. As mentioned, stage 1 tunes will not get rid of the CEL and catted downpipes are no guarantee either, especially as they age.

Agree.
You also get a lot more features, smoother power delivery and control with the stage 2 tune ( code reading and deleting, datalogging, boost by RPM, Boost by gear, etc...)

I've seen no evidence of the stage 2 tune giving smoother power delivery, seems to be the biggest gripe actually. Power wise and best at dragstrip, yes, the stage 2 with downpipe and better gas can't be beat, but after 3 cars and 6 years on this forum, smoothness of power deliver is not what I'd say is the reason people go with stage 2; all other reasons mentioned yes. Perhaps this is true for JB stage 1 to 2, but the JB stage 1 is not even close to as smooth as the RaceChip or the AA8, I've tried all 3 stage 1's. If going catless; correct get the stage 2.

Any stage 1 tune adds the same boost amount across the RPM range ( anywhere between 3.0 to 4.0 psi).
With a stage 2 tune, you can control your boost each 500 rpm.

With the ability to do so, you can adjust / lower the boost value at a certain RPM range to get smoother delivery.

This has nothing to do with which brand the stage 1 tune is.

I never said that the reason why anyone would go with a stage 2 tune is smoother power delivery. I just added all the extra features that a user get when getting a stage 2 versus a stage 1.

Example: instead of adding 4.0 psi as soon as user goes WOT, you can add .5 psi each 500 rpm and get a smoother power delivery.

Well you said exactly "smoother power delivery" so not really any room for misinterpretation, but the AA8 unit allows for RPM boost adjustment as it is a stage 1 with 3 sensors, one being the cam. Not looking for endless argument, I'm sure stage 2 is great for numerous reasons mentioned, but stage 1's can also offer very smooth power delivery, but can't clear codes and aren't fine tunable to various mods (fuel, downpipe, etc) I've actually found a notch below the default value of the AA8 unit with hi-flow catted downpipe produced the best results on the street for power delivery. I'd guess the stage 2 JB would actually up the boost with downpipe and fine tune things better perhaps.

Not sure what that meant. Yes stage 2 gives you smoother power delivery because you can control boost by RPM.

What I meant was the fact you said "I never say the reason someone would choose stage 2 is for smoother power delivery" just using your words, no big deal if that wasn't what you meant.

But, it is also not true that all stage 1's have constant boost change all are RPM's, as I've stated and is a fact, the AA8 unit adjust per RPM using the cam sensor. So nothing unique about that to just the JB stage 2. Other features mentioned are correct if that's what you are looking for, but in terms of RPM adjustment of boost the AA8 does this as well and it's a stage 1 tune.

You are correct about the A8 boost by RPM control
