General Supercharger Thread

They were from Amazon but from Densos direct page.

We just checked and found they weren't actually gapped at all AND Cylinder 7 was barely tightened at all. Gapped them all and obviously tightened 7 properly. Took her for a drive. Right back to limp mode. Just moved the coil and plug from 7 to 5 and still got a failure on 7.

 

I'd clear any codes then disconnect the battery for a few min. If plugs weren't event gapped etc I'd be going through it all checking connections as well.

 

We did clear codes between all test runs but didn't disconnect the battery. I left for now but just texted him to disconnect the battery for 15 mins and take her for a spin again.

 

Call me a prude but I still don’t trust Amazon, even direct pages.

Hopefully @reywcms suggestions fix it; I was going to suggest doing the same thing.

When you say ‘not gapped at all’ do you mean that the electrode and ground strap were touching? Or simply incorrect? If that one plug is giving issues, I’d look at a bad plug from being dropped or mishandled. I’ve cracked porcelain on a plug that only misfired when hot, but ran great when cold. Plugs are relatively cheap. I’ve had good luck sourcing from RockAuto or local parts stores; exceedingly poor luck with “genuine parts” from Amazon, including spark plugs.

 

My mistake, I meant they were untouched out of the box. Not gapped to spec. Moving that plug to another cylinder didn't make the failure move so I don't suspect an issue with the plug itself.

I actually have another set of the same plugs sitting here we can swap in if it comes to that though.

 

But an initial finding a loose plug lol leads me to go through all items installed lol

 

Same result after a 15 minute battery disconnect

 

Limp mode? Is the maf etc plugged in? What tune is in it? Did they have an issue loading the tune at all? Who did the install?

 

They did have an issue loading the tune but I figured out the issue and was able to load it successfully. It's the Whipple supplied tune. The original tune was based off a non stock tune that was on the truck but I was able to reload the stock tune and pull it and get it off to Whipple for them to redo their tune off of, which they did, and I was then able to get that loaded successfully. Andrew, at XAT, did the install.

We drive it and it pulls ok under moderate throttle and then right about 55-60 the truck starts shaking and throws check engine and the code is always misfire on cylinder 7. Maybe 'Limp Mode' isn't the correct term but we sure do limp home.

 

Hmm a non stock tune to base a tune from. Lots of variables here we're tracking. If it were me I'd flash this thing with a stock tune and drive it see how it acts. IT should drive fine. Then have new tune loaded etc. Then start going through all the install mechanical items. And I'd drop the plug gaps down

 

On it tomorrow.

 

Maybe missed it but did you swap coil too? Check wire connections on 7. Could not be producing enough voltage under load but fine when cruising.

 

Yup. Moved coil and plug to see if the misfire moved with it.

 

After every tune i do my truck runs rich as shit. If i wot and hold down the throttle it will throw a code and start misfiring. Ive learned to get some miles in. Tune always starts to lean out and settle after 100+ miles. Figured it was the KCL and knock doing it's thing until it settles. Now is that right and should it take that long to learn up, I don't know. Just my situation after every tune. What air/fuel do you see when going into limp mode?

Here is a good read on the hp repository about learn up from SlowNstock for anyone curious also

 

Missing spring?

 

I noticed you mentioned you have headers, where are your primary o2 bungs?

 

No headers on the 2019 yet

 

Loaded the stock tune. Issue gone. Rey nailed it.

So, basically... Fuck the Whipple tune. Done trying to make that work. Getting the bung and gauge setup ASAP to move forward with Sniv doing the tuning. Already got him the stock tune. Just need some real logging now.

Thank y'all for the help.

 

Boooommmmm

 

Pink wire on the traction control button on my '21. That was a huge pain in the ass, those wires are paper thin. Got it done though.

 

Nothing like throwing the kitchen sink at it. When all it took was a "when did it last run fine/what changed". Glad you got it figured out and a good plan for @snivilous tuning.

 

AWESOME!! They are incredibly thin wires, for sure! Thank you for the follow up!!

 

That's nuts the Whipple tune is that shitty! @snivilous tune will make that shit purr....

 

Not that I'm defending Whipple, but it's got to be something else other than their tune or a culmination of things. I've driven in all scenarios for the most part; wot from a start, wot down shifts street/highway, stop/go traffic for an hour(etc..) and recently a 3 hour non stop drive which yielded 17+ mpg. I have a 2013 though, so unsure if any difference in the tune received between years non ff. My .02..

I would certainly be on here frustrated and looking for a new tune sooner than later.

 

This isn’t a Whipple issue this is a corrupt broke initial file issue. And install error of plugs and sensors.

 

Could use your guys eyes/brains before i reach out to whipple.

Here's an album with all the different parts that it came with

I went through all the boxes/bags to make sure i have everything as i may be able to do the install next week.

Here's the Packing List:

Page 2


I'm assuming i dont need 3.0L Toyota Discharge Plate, or any of the stuff below "GM THROTTLE STICKER"

From the Belt System Parts bag, i'm missing a .390 Step Spacer



From the Intercooler Parts I'm not sure about the Fill Tube Cap, or those 3 small brackets below the IC pump. The pack slip just has 2 brackets


Looking at the IC install instructions, i think i've got everything i need



Other than that, i'm missing some decals, 91 octane sticker and the CARB sticker....i'll reach out to whipple and ask for the .390 step spacer, the carb sticker, and the decals.

Here's some blower porn:

 

Crazy they can't send all the parts. Is the IC pump smaller than the Bosch that comes with the Maggie?

 

Not sure, the one that came with it is a VariMax pump.

 

Check the idler to have the stepped spacer. Fill tube cap I just used one I had laying around some also have a tube to that and dumped Incase of over pressure. Intercooler brackets look all there.

Intercooler pump flows more than the Bosch Maggy pumps just a different brand than those standard seeing.

 

@Danimal86 You're definitely missing the stepped spacer; I was missing the same stepped spacer in my kit.

The fill tube cap is just referring to the cap on the coolant reservoir; I asked Whipple the same question.

2017Tund-BOLT4004-01 parts bag was superseded by -02.
