*Closed* 20% Off Supercharger Group Buy 2nd Gen 4.0 Engine

I did the OEM FPR mod this morning. It definitely richens up the AFR at WOT a little. It would be fine like this, but in my opinion the truck seems more sluggish when not in boost. Instead of a solid 43psi at all times like before, the fuel pressure is like 33psi at full engine vacuum and gradually goes up to 43psi at 0. Then climbs up close to 50psi at WOT.

I'll most likely be putting it back the way it was. I'm out of boost more than in.

I have the 2.85 pulley and the BD tune did not work.

 

Would be interesting to set up a poll, for: year, transmission, pulley size and whether the BD install was successful.

 

For the most part yes. Unless im lugging in a higher gear and its pulling 3psi before down shifting it will stay in the 14s but first chance it gets over 3k rpm and has reasonable boost those afr reading plummet to 10s

 

I wasn't sure how to word it properly but this is basically how my truck operates.

 

The thing on four black doughnuts goes WHEEEEEEEEEE and the thingee with colors goes whomp.

 

Yeah, those were the words I was looking for. It's like you can read my mind.

 

I just ordered 2.825 pulley this morning... and i wanted to stay with BD...
what was wrong with your tune and what did you do to fix that?

 

The truck went extremely lean. Like 17-18 AFR under boost. What I did to fix it was uninstall the Bully Dog tune and visit the dealer for the TRD flash. Dealer claimed they couldn't flash it, but truck has been running good ever since I left the dealer.

If you've already bought the kit with the Bully Dog, go ahead and give it a whirl. It may work for you. A few of us have had some issues but most people seem to have no issues.

If you haven't purchased the kit yet, I would get the one without the tuner and visit the dealer for the TRD flash after you install the charger.

 

I bought full kit from guy who decided not to install SC. so i will have to deal with BD. will try....
do you have any intake or exhaust mods?

 

I have an AFe Stage2 ProDry S intake. No exhaust mods (yet).

 

im getting nervous... so many expectations... i feel like i'm a kid who is waiting for his Chrismas gift

but so many bed signs... a lot of guys have problems with this SC.... i do not want problems, i want to ride..... and boost of corse

 

I understand the feeling, brother. Are you installing yourself?

 

yes, urd pulley will be delivered friday, and i do not want to install in over weekend, so i will do install next week. if my work will let me do that.

 

Cool man, just take your time and follow the instructions step by step. The install is pretty straight forward.

 

I'm telling...

 

The nice thing is, many people here have done all the troubleshooting for you should you run into any issues.

 

Truck is at the dealer...

 

I concur as well, Dr. The system is performing as desired. I have been satisfied with my purchase.
Prior to the supercharger I had stepped up to 285/75 17 (34X11.50). The performance change wasn't that drastic even with a load range E Falken Wildpeak AT3/W. Heavy! I already have added a topper, tools, Hi lift, Steel plate bumper, skid, sliders... So its been a slow death of acceleration.
The UCON prior to install already made a big difference in performance. Now I have a new truck. Can't wait to do the next mod. The paradox of wanting and acquiring is depleting my accounts.

Just spent a week in CO over the holidays and took some time for wheeling. Went to some old stomping grounds in Pingree Park. I used to bring my 97 Taco up there +10 years ago. It was nice to bring a newer, bigger, badder Taco!! Snow was deep and I'm without a winch, and the SC helped power it through some nice drifts and up some steep slopes.

 

Gave up on trying to figure out the issue with the p219b code. It's a air/fuel ratio imbalance on cylinder 4 is what I was told by the dealer. There is a TSB for MY 2015s on replacing the heads. Not sure how this is going to work out for my truck. Basically was told by the dealer is low compression in cylinder 4. And in order to determine if it's covered under warranty they have to pull the heads and have them inspected. If they determine it's not covered under warranty I have to pay the labor. Bummed about this whole thing.
I'm not saying the supercharger is the issue and not trying to scare anyone. Just wanted to keep everyone informed on my situation.

 

Ouch, Man. All the best...
