No gain adjustments or anything else you need to adjust on that amp? I like to be able to access mine.
It has a dip switch for 2 or 4 channels, a high pass filter for front and rear (off/60/90/120hz), and gain front/rear. I'll have to pull the head unit to tweak gain, but I'm not constantly driving these speakers so I'm not that worried about it. But I can adjust the gain without removing the DD mount.

the one i bought had 4 credits...
Costs a little, but it sure keeps me interested. :)
Wifes car needed updated injectors and an update from the dealer.
Did the injectors and updated the injector prams via hp tuners.
w00t!

Not quite liking how a shift feels etc, put it in M and play with the limiter (6spd), or hook up hp tuners to a laptop so i can see what gear and adjust.

Also Imagine not having a dongle sitting there.
Downside, costs $50 per module to add.

however in these vehicles there are only two (don't let hp tuners sell you on a third).
Or you can just do the one module for ECM @ $50 and turn off DOD.
then let the TCM module nag at you later down the road.

:D

Well i had a mini heart attack... lol

Me dicking around with the tech 2, seeing if i could see anything funky with my driver side heated seats before i drop the $70 on a new switch.
(Sometimes i have issues getting the butt + back button to activate, but the back activates just fine).

Clicking buttons, suddenly i get a check engine light when attempting activate a module i don't have.
Tech 2 being a pita to pull a simple fkn code if your not sure what module, i whip out ol trusty.
P0700

Trans seems to go into gear fine, so i'm thinking the tech 2 did something weird while i had the engine running.
I clear the code for good measure, then i swear i hear a new noise.

Not from under the hood exactly, but more like under...
Like oil pan area, but back.

Me: fk i knew i should have changed the converter while the engine was apart and easy to pull... :rolleyes:

so i disconnect the battery for good measure... let everything reset.
Took it for a little spin real quick, seems to go into lockup just fine, fluid looks fine.


probably just a strange fluke, but man those "while i'm in there" tasks.
It's always the one you skipped... :jester:


I'll let it drive me nuts for the next little while... :hahano:

@Doubeleive
What is the "Upgraded and Welded Drum"?
I understand that there is a clutch drum that's known to pop/crack, maybe a reinforcement is added?

ETA: t104741qk = the TCC valves that go with the transgo shift kit.
Good stuff, a very noticeable difference in my 6spd :cheers:

Ya he showed me a stock one and then one that has the weld added, the stock weld is pretty thin he said they come apart right there and the weld fixes that

I was messing with my laptop connected with the Tech2 as a pass thru and saw my HVAC control had an upgrade for the firmware. I love free upgrades I’m thinking. It was working fine but ..you know. So halfway through flashing it the display went blank and the process hung. For hours. So I called GM tech support and the nice woman on the line had me disconnect everything, disconnect the battery, re connect everything and try again. No luck. It was bricked. I found out later it was my Pioneer stereo- the process hung when it tried to communicate with it but since it was aftermarket it couldn’t. ( Disconnect any aftermarket electrical stuff before programming modules is the lesson here) The price for a brand new module was about $250 I think. I bought a used one from LKQ for about $40 luckily. I didn’t check to see if it had a free upgrade lol. It works just fine.
