They can't get you busted. What you do can. But it is for off road use only right
They all with disable everything, change almost any setting and allow you to tune to perfection if you dont break it first.
I bought mine for $501 with 2 credits. 2 Credits allows you to tune a black box or 0411 all you want but only for 1 ecu. Newer trucks may require more than two credits.
Ill never be tuning a newer truck but will eventually tune my 0411 so will need to buy 2 more credits $100.

$125 a credit for EFILive, 1 credit per vehicle regardless of generation as far as I'm aware. That gets you the ECM and TCM in the newer stuff.

About the same. HPTuners is 49.95 per credit and 2 credits per ecu. I think TCM included but not all. 6 of 1 half dozen of the other.

Right, but didn't you say newer vehicles take more than 2 credits?

Some do i think like 2018 and newer for the TCM, but i did not look into it much as i never plan on having one that new personally. Newest ill ever consider is probably 2015 or so.

What is the point of turning off the rear O2's? Black bear said it's often done when using long tube headers, but why?

Eliminates the CEL. Usually it's because the cats are removed.

Mine has healthy cats, should I keep them on?

If you want to continue to know that they're healthy, yes.

I have made a lot of progress, but also some setbacks. The fuel system is finished. I cut off the pos stock fuel press regulator and brazed on a -6 AN male nipple. Cut off the fuel lines just past the fuel filter and brazed AN nipples on them too. I used a -6 PTFE braded line on the fuel into the reg, and a -5 line on the return. The new holley regulator is mounted to the firewall along with the coil and coil driver. It came out really clean and leaves a lot more room over the dist.
