SasQ I&II delete were my first mods 5 years ago, and I've survived fine with the egr code without doing the adios-flash. The plan is to add that e-delete to the other 3 performance flashes... IF I ever get this donkey-pile of mods I (stupidly) saddled-up to bray.
I've been wrenching for over 40 years and I've never been this abused by so many stupid little problems.
Example: Yesterday, I was wrapping the install of a pioneer media head. After installing 2 amps, 8-speaks and a rear-cam, the FINAL procedure was to install the fascia-plate around the head. I barely grazed its p.o.s. plastic %#@& front knob with the fascia, and it pops-off. With the interior still removed for deep-cleaning, it still took me an hour to realize that it had managed to ping-pong into the abyss within the tcase lever housing!

Another hour and a dab of caulk on the end of 1/4" socket extensions to coax it out only to discover that the knob's mounting tab had cracked. Replacement? 37 @%#& US Dollars and 3-weeks! $37 bux for a small plastic knob! Grrrr...
I suppose the "upside" is that it was JUST the knob and not the head's spindle but I'm not feelin' it.
Seriously, endless infuriation. I must have pissed somebody off in another dimension...
After 10 months, start-up is still ahead. Optimistic?
Moral: Be Smart; enjoy your VALUABLE TIME going on excellent adventures in your STOCK jeep.
