I will buy it right after I'll get SC, i do not want to remove belt and change anything later. better to do the right way from the beginning

Agree about tuner, there is no reason to keep it when you done!

 

Unless you're going to change pulleys - there's a different tune for the 2.85"

 

it is good to know that!
Maybe it is a stupid question or it was discussed before, but do that tunes included in that tuner? how does it work? just choose your sistem and uploade right map?

 

Theoretically, yes. Bully dog has a tune for the stock 3" and also the 2.85. I didnt see one listed for anything else. I had issues from the beginning with mine though but seems like for most it was smooth sailing.

 

Empirically, it appears the issues people have had have been with stored settings from prior to the flash (fuel trim settings the likely culprit). If the ECU clears its learned settings those troubles vanish, as was probably the case when you had the dealer connect it to the Techstream, or when others disconnected the battery and drained the ECU.

Not to say there aren't issues with the bully dog tuner - there are - but the tuning file is solid IMO.

 

I may revisit the BD for the 2.85 tune later on, but not until I get my Mongoose and access to Techstream. We need more people on board to get the Mongoose group buy rolling.

I liked that post, then unliked it, so I could like it again.

 

Idk, I think i would rather have a UCON eventually when they become available.

 

Gadget said he may have some stock available toward the end of the month.

 

That UCON is a pretty sweet piece of kit - but after bolting everything back together after the SC I have no desire to tear into the engine and replace cams. I'll enjoy the basic boost for a while - at least until my clutch gives out

 

Ahhh true. Forgot about the cam gears. I'm not ready to tear into that either.
All I want is a tune I can be confident in. My truck runs "fine" but it doesnt seem like everything it could be with the right tune.

 

I honestly don't think there is anything wrong with the tuning file, even if the BD tuner itself is a steaming pile. It may not extract every bit of power available but remember the TRD/Magnuson blower is designed to be reliable - when you get close to the edge with small pulleys, leaner mixtures etc. you start stressing the motor and your bulletproof 4.0 is no longer so bulletproof.

Just my $.02

 

I'm not 100% sure but when I was looking at the red pulley it said it was for the URD SC. I wasn't sure the differences so I bought the stealth pulley. Make sure you confirm it will fit on the Magnuson before you purchase.

 

How is this working out for you? Can you feel a difference? Does the whine tone change?

 

The "best" solution IMO is to have both. UCON for performance and TechStream for everything else. Look up the capabilities of the TechStream. A lot of visits to the dealership can be avoided and the TechStream makes maintenance and diagnosis of problems a heck of a lot easier.

For example: the TechStream will allow you to activate the brake hydro pump (or whatever it's called - I'm brain farting at the moment) to allow one man/one button touch brake bleeding, so sitting there manually bleeding brakes becomes a thing of the past. I wish I had one for yesterday.

 

I plan on getting a UCON later on. Probably not right away though, because similar to what @TaterHarry said above I'm ready to take a break from messing with the engine. Wheels/tires/suspension are next on my list of to-dos and maybe some audio upgrades.

 

Seems like I may have a issue. On my way home from work tonight my supercharger/truck was acting up. I went to punch it and truck started to feel like it was bogging/loosing power. My afr gauge shot up. Seems like I'm not getting enough fuel. My tank was around 1/4. Thinking the line in the tank from the URD fuel pump kit may be kinked. Any opinions what else it could be.
Edit- I did disconnect the battery for a few hours to mess with my intake. Will having the battery disconnected clear the BD tune from the ECU

 

I disconnected the battery to clean my maf due to a p0101. I'll drop the tank and check the line this weekend. May also take it to Toyota to get the trd flash. Hoping it's just the line from the walbro 255.

 

While you have the pump out, grab a unibit and drill a new hole in the top of the bucket for the fuel hose to make more of a straight line to the nipple on the upper plate. Here's mine.
