Big night last night for Big Brown. She got a quadzilla with stealth cover,  tranny flush with amsoil, replaced my leaky cracked oem wheels with a set of 17” 4th gen wheels that came with good used hankcooks for $150!
 

I did hit a couple snags though. Anyone ever seen where a BD boost elbow is too large diameter and won’t thread into the turbo? Also for most of Me78569 how much fueling should I add for 3500 ft? I took the truck for a spin at 1am and didn’t have quite the punch I was expecting from a few of the tunes. 
 

PS ignore the mess, I just moved in and still organizing things and doing some renovations 

Add fuel until you are happy

What would cause a dead pedal feeling? I’ve got balls to the walls loaded and seems like after quarter throttle nothing changes. My apps is showing full 100% position when I floor it though 

There’s a definitive drop off where the rpm rate it increasing and then drops off and it plots along 

Also getting a max of 3psi, checked all connections and looks like I don’t have any leaks and I should hear one that big? 

I had an issue with my boost elbow not fitting.  Returned it and got another from XDP and it wouldnt fit either.  I got my tap and die set and made it fit. 

 

I emailed XDP and told them to check their stock, that I think they had some elbows incorrectly marked but I never really heard back other than the obligatory "thanks for your email" email...

Sounds like your map sensor is not working well.

Ok best I could get out of the map sensor was mid 14s. Where should I start diagnosing if it worked fine before the quad?

Pulled the quad off and plugged factory in and it runs perfectly fine 

And map codes with the quad connected?

 

Your not using lvl 1 are you?

No sir, no codes factory or with quad, and I’ve cycled through about 4-5 of the ones from the repository and all act the same. Haven’t tried the canned tunes on the quad yet 

Not sure if this helps or not but I tried leaving the quad all hooked up except the map sensor plugged in factory style and it acted the same with no boost or throttle 

Maybe you got a bad Quad. Might want to give them a call Monday if you don't get it figured out.

Well crud that’s a bummer 

It definitely has symptoms of a failed sensor or missing signal. Though if it had failed I would you would have a CEL lit. Could be the Quad.

Not sure what my next step of diagnosis should be if it works when the quads not part of the equation?

If it works fine with the Quad disconnected I would say your next step is to talk to them. Sounds like the Quad is not picking up the MAP signal. Yours is driving just like mine did when the MAP sensor went south on me. 

What level do you have the quad on?  

 

If you are running lvl 1 of the tune it will do exactly what you are saying.

 

Lvl 1is valet mode.

Sorry if this is a stupid question but are there multiple levels on a custom tune?

Yes.  Even custom tunes have different levels. 

They all follow the same format:

Lvl 0 = Stock

Lvl 1 = Valet (set to some decreased power)

Lvl 2 = Timing only

Lvl3 = Timing and Canbus fueling

Lvl4 and up is wiretap fueling

Small correction.

 

Lvl 2 = Canbus fuel only to 100% and timing. 

Ooohhh gotcha! I assumed the power levels were just for the base canned tune and not on custom tunes. She runs like a top now that I turned it up! Thanks for putting up with my slowness
