TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

“Or nitrous systems..,”. Boom!

 

The FPR mod increases fuel pressure as boost goes up. If fuel pressure goes up, AFR should be a little richer.

Here’s the quote from the first post

 

During the beginning of the pull, the AFR's stayed high. Then shot down to the 12 - 11's. From there they are steady between 11-12, except during shifts where it richens up some. Looks good overall.

Edit* Loginfailed beat me to it.

 

Thanks, weird I got Unsubbed somehow and could have sworn it had ovtune in the title so I couldn't fine it. I'll be getting @GT7 's handheld soon

 

Im sitting here at 4400 with me in it.

U guys need them smaller pullies bigtime

 

It's a fact

 

Ill say, ur well above my gvwr

U regularly haul a mini cooper in the bed?

 

That’s a suggested GVWR

 

And I regularly tow a 6k lbs travel trailer. Lol that is where I am all the sudden scared that I have been washing my cylinders. Cause I run in the boost a ton! Or did before the new gears. With the 4.88's it is like a whole new truck. Tranny temps are down 50 degrees just driving around town. And down almost 80 degrees with a small 2k lbs trailer.

 

I have the 4.9 sensor. I will order a Denso and see if I am truly that rich. I do have the URD Spec.U equal length headers with the A/F sensor extensions so the factory sensors are in the collector not just the middle bank tube and the AFR guage sensor is right behind the factory one on the passenger side. Would anyone suggest moving it? Or moving the factory sensors back to the center cylinders?

 

Definitely not in the center cylinder or you'll only get a snapshot of that bank's performance.

 

Thst is what I thought. That is why I bought the extensions to move them to the collector at least. The Doug Thorley long tube headers I had on before these only had that option. I never liked that.

 

If the gauge continues to fluctuate and freak out on you giving E8's, plan on getting an AEM gauge. I would not trust an innovate gauge as far as I can throw it these days.

 

I'm in process of aem gauge install. Am I correct to understand the bosch o2s it came with are poor? If so where is the best place to buy the right one?

 

There are part numbers on the first page of this thread. First post as a matter of fact. There’s also an Amazon link to the one OP used.

I’m going back to check it out now. My Bosch is dead.

I may have the deaded coolant leak from my resi. I saw it crusted around my hose clamp on the lower hose (drivers side). Is this the same problem everyone else had???

 

Sounds like what I have at a few of my joints. Been like 2yrs and the level hasn't gone down enough to even warrant a top off. I just wipe the crustyness off whenever I am cleaning the engine bay and call it good

 

You add nos to yours already?

 

Same here. I added maybe 100mL this afternoon for the first time.

 

Yeah, that’s what I did. I’ll obviously keep an eye on it. When I go to do my CSF radiator and drain the system I’ll inspect that joint further and replace the hose/clamp if needed.
