Had some good luck in the last 3 weeks and I suddenly have money for a Quad and I have a few questions.

   I have a fuel pressure gauge in the truck already so is there any real reason to get the fuel pressure sender for the Quad? 

  I have RV275 injectors and a stock HY35 with a spring on the waste gate and make about 28 psi max.

  Trans has a stock rebuild on it done about 25,000 miles ago.

  I'm not looking to make 500 hp or anything I just want 275-300 hp. 

  The most important thing right now is fuel mileage. I'm getting 12.5-12.75 right now.

  Is there a tune on here that anyone would recommend for my combo?

  Is there anything I need to do before installing the Quad?

  Can I just put the Quad in without hooking it up to a computer or does that have to be done before use?

  I do not plan on the wire tap at this time. If i do it in the future i will use a Stealth Plate.

  Thanks for any help and please feel free to give me any advice that may be helpful in getting this thing up and running.

I could get it up to about 4 psi on the mechanical but the SGII reading was stuck at 14.6 and did not move. As far as the truck brain goes it was seeing 0 boost and would not fuel very much.

 

As far driving, completely gutless. I could cruise the interstate at speed, 75 mph, and accelarate very slowly on the flats and slight slopes. But you would have to take run at a 2% or 3% grade. Any thing over you could do but you better be in the slow lane. No fun but better than sitting in a motel another day.

Anyone recommend a could quality android tablet to go with one of these Quadzilla's?

Any thing with with modern Android version 9.0.

I'm using a gen 5 Kindle its 4-5 years old and works great. Just have to Google how to install Play Store to get the Quad app.

I think the app says it'll work with 4.4+, but I had trouble with 4.4 and Version 5. I've used 6, 8, and 9 without trouble.

Wondering if you had a quad, if a guy could create a tune to run stronger with a failed map senso just to get by. @Me78569

I think you asked the right person about that. Not sure how the Quad uses map info. But I would think it works in tandem with it.

A map sensor stuck at 0 really limits the fueling from the ecm.  Its really a limp mode.  You could throw a ton of fuel at it and a ton of wiretap but it wouldnt drive nice.

 

A map sensor that fails low puts the ecm in a part of the map that was not designed to move down the road.
