FYI, I had to add to my SC coolant several times after the first several start ups. Not alot, but several ounces 2-3 times to bring it up to correct level. I have a 2020, and 5k on the maggie and it runs excellent on Daves tune.

Ok, now for the question, is it worthwhile, and how?

Is there any way to do a cat delete? We don't have sniffer test here in WV, so I could easily get away with it. I've never ran cats on any of my Z06's.

Knock on wood, you and I, and I'd say a few others have been lucky. I have 5k on my magnuson now, and have had Zero issues re: the SC. I was having high issue idle, and cel, and all along seemed like a vaccum leak. Low and behold, the VMV hose from the intake to the purge valve came off behind...

Gotcha. See if the dealer will give you previous owner contact, and call them up to ask them. If they won't maybe a carfax and some googling will find the previous owner.

So is it supercharged, or was supercharged and removed?

Nice report, and I'm sure one helluva trip! My SC is the same. I have 5k miles, and only issue I have, which just arised 500 miles ago is a jeep issue, and not a SC or Dave tune issue. I've only towed once, my OP4 with gear to the mountains. My truck is on 39's with 513s, and it pulled the...

What tune are you running? I have found my truck runs best on Daves 121 tune. Have tried all the others, but this one is best overall. Smooth as butter, and great power all over.

Funny, my local podunk dealer here in WV says they do atleast 2 a week.

Yea, I'd walk, and not worry about it.

I bought a used Magnuson as well. However, My experience was better, the fella I bought mine off had every single part labeled to each step in the manual, and even sent extra hoses, pulleys, and fasteners. He offered me his unlocked pcm, but I already knew the vin could not be changed. I have...

Will be a cool experiment to find out exactly how underpowered the JT is!! lol Nothing wrong with running on a dyno, I've had plenty of corvettes on the dyno, albeit for tuning, but it wont hurt anything just to put it on the rollers.

I do and don't miss those days in the hay field!! lol

He did not. I was going to reach out to @DAVECS1 and see if this could be done with HP? If not, I am guessing they can do it at the dealer? IDK? I got off the phone, and thought shit, shoulda asked more about that.

Was confused on that as well. Tech explained to me that there an output reading on the ibs in the computer. It needs to read above 84% output from batteries for everything ti work properly. Said he’s changed a dozen or so the last few weeks and they’re either stuck on 60% or 80% output. Makes no...

This is the light I have with the high idle issue. I put a new TB on, didn't fix it. Did IBS reset, didn't fix it. Battery is fully charged, still there. Dave has not been able to tune around it. Spoke to Service Tech manager today, and he wants me to gauge out put of ISB module. Says they have...

I ordered a new one from my dealer, and had it the next day. Didn't fix the issue I was having tho, so a waste of $250.

Gotcha, very cool! Our mal just turned 6. My good friend has a dutchie, and my brother in law has a corso. All great dogs!

What? 19k for 3500-4k in parts isn't reasonable?!?! lmao

I'm just quoting you to ask if you really have 5 mals?!? Our 1 is enough!! lol And just to contribute to the thread, I have an 18 colorado Z71 work truck. Biggest turd of a vehicle I have ever owned! The new one doesn't look bad from pics, and the 2.7T should help, but at the end of the day...
