Ddp is overpriced Garbage.

 

If you want to spend big buck on VP injectors go to Winston over at infinite performance.  If you want good budget injectors go with dap.

In 4000 ft and higher. Would you use there 75hp Injectors with 58/65/12 turbo and a quadzilla? I have 100hp ddp now and struggling to getting it to run clean

 

 

 

I would run 7 x .010's and a quad.  

 

my 7 x .012's (~200 hp) DAP injectors ran MUCH cleaner than 100 hp DDP's

 

DDP's use the wrong spray angle causing fueling to spray outside the bowl resulting in smoke and heat.

Weston Shupe's injectors are not pricey considering you are getting the best. I have been running his 6x13's since July of 2015. Never have had a problem. Just got 22.6 MPG driving normal @125 kph (77.6 MPH).

Are you running oversized tires? That number will be worthless. You'll need a GPS to track mileage correctly. MPG number have to be done with either GPS or with a calibrated speedometer that is verified. 

265/65/17 -  30.5'' tall  

 

Did you re-calibrate the ABS? For that rev per mile?

No, unless the Smarty left it behind. That's the only time if any was there some sort of recal done.

Smarty has been gone for at least 2 years now.

Why do you ask? Does something not add up?

I wouldn't worry about it.

Why would recalibration be needed for 265/65/17s? Isn't that about as close to the same diameter as the stock 245/7x/16 tires as you'll get? Or is it recalibration from a previous calibration to taller tires?

 

Since I don't like to out tires on the max-width wheels, I was going to try the above 265/65 in stead of 245/70.
