Dyno tune has much more potential...since you can see the air/fuel you can run it more on the edge and make more power, but mail order they gotta leave more of a buffer zone before detonation and whatnot since they dont know how it runs with it and with the air density and everything

He did a good job on the WOT throttle stuff I'm just picky and don't like seeing a lot of the other things in the map, he's not the only well known guy I've seen the same things from. I typically overkill the low fuel/timing maps so the car can make huge corrections if needed and I don't really like messing with the knock sensor unless it is 100% absolutely needed. The idle, I don't know what to say about that, maybe it wasn't covered/reported how poorly it idled. I don't even like to use the stock idle tables on a stock car, so maybe I'm weird. I like an EVO to idle around 1,000 rpm, not 800, especially with cams in it.
Well that's good,Because we both know people would be questioning there tune and giving the guy hell..

Something else, for those of you with cables, do yourself a favor. Just take a few minutes to look at your maps, the high/low fuel tables should not be the same, the fuel table numbers should be at least somewhat richer. More importantly, the high/low ignition tables should not be the same, low should be lower numbers. For the old maps with multiple high/low tables make sure the highs match, the lows are lower and they match also. That car yesterday had the top end of the low timing map set higher than the high octane map, bad mistake.
the ignition map is pretty important.. that should always be set lower then the higher.. and as you said not just changing spots on the map.. actually highlighting the entire map from right to left and stopping around 100KPA and dropping them down a good 3-4 deg .. same with fuel.
as far as idle goes.. why someone would make big cams idle at 800 is beyond me.. idle is the easiest thing to tune in these cars.. bump the timing up and set the threshold higher in the RPM table and done.. then work your latency out until you get your low trim inline and stable stft's.
also id suggest people to open their roms also.. how smooth are the maps? view them in 3d.. is the fuel map staying under 13-14 values on the far right? is the timing map smooth on the far left and in general everywhere?
as far as cars dying with AC.. tune the ISCV to compensate for the additional load the AC puts on the engine & bump up the ac idle tables.
you posted an example of a bad remote tune, i have dozens of examples of dyno tunes as well gone wrong.
its one of those things where it depends on the person doing the work and how they did it that day.. ive seen work from the same tuner where one of his roms would be really bad, then a few months later much better.. like they learned as they went and got better. it happens.. no matter if they are a remote, road, or dyno tuner.
Id also like to add:
Its human to make mistakes, and anyone who claims they don't ever make mistakes will get no where in life.
Someone who is always open to learning something new vs someone who feels they have nothing more to learn,
the person who is open to learning new things has a big advantage over the other person that feels he knows everything.
Of course i am the open to learning person and i know David is also.. Looking at older roms vs newer i see a lot of things
Ive progressed over the years as well.
Basically what im getting at is, good tuners can make mistakes.. as long as they see they made that mistake and dont continue
making that same mistake again.. humans learn from mistakes by nature, so as long as you can learn from it you're still ok in my book.

So I changed the plugs back to the Range 7 and did a boost leak test BOV was leaking at the flange made a new gasket and put rtv on it. The car also was leaking on the LICP if I touched the pipe it would instantly leak, Runs good @ 23 psi now

I have a dyno tune. My brother (speed3) had the email in tune.
Here are some pro's and cons of each.
Dyno Pro: Fast, Easy, Accurate
Dyno Con: Cost, If something isn't right with your car and you end up with a bad tune, there is NO time to fix it. You have to go home, fix it, then bring it back to the tuner and pay again to get it tuned. This leads me to the email tune
Email Pro: TONS of flexibility, if the tuner sees something funky, he instructs you to fix it, and then another pull.
See, with the email tune, you can have alot of time in between pulls to correct/fix anything with your car. (days, weeks sometimes) At a dyno, you are very limited.
Email Con: you could get a ticket when doing your logs, takes longer.
