So you lost about 300whp in that deal huh, must have been devistating.

 

This was in my auto truck with a single turbo Pro52. You're right about gaining more boost with the compressor upgrade. Although I've never done a compressor upgrade, I've done a few complete charger upgrades and each time I made more boost with each step up.

 

i gained no boost when i added my compressor upgrade...

i see over 40psi with my set-up when i am not in valet mode and about 35 when in valet mode.

 

One thing you should know is my elevation is around 4200 feet, so I will see less boost and longer spool up times than someone near sealevel.

My pump is not cranked. I have one of those pumps that dont respond to the full power screw. I think it got up to 1100 during the WOT test, it made some smoke, but not alot. I also think my trans is holding me back some. When I get the TC installed, it should hookup better.

 

About how much is a set of these DDR injectors

 

$749 for the 80 horse injectors, no core required.

 

Yep and I'm impatient so I paid the few extra dollars for second day air delivery. So total was like $770 and arrived a day and a half later.

 

it's fun, huh? tc

 

heh heh, this is what happened to me. I originally purchased the 40 horse injectors, but when UPS tried to deliver them I wasn't home, so they got sent back. So, I called DDP up and asked if I could just pony up the extra $200 and get the 80 horse injectors instead.

 

Thats weird, here it doesnt matter if your home or not he just puts the package on my porch and leaves. then again my dad does get a package in once a week almost.

 

Up here the snowbank is close enough for a delivery. No kiddin.

 

So, the DDP 80HP injectors are really 4 hole injectors? If wanting to gain 75-80 horsepower from injectors is it better to go with a 4 hole or 6 hole (like what the stock injector is)? Sounds like the DDP series of performance injectors give you the best of all worlds in terms of higher performance power, not much smoke, and efficiency is still there like a stock injector. And the price sure does show it too! I'd love to go and place an order on some of these injectors today, but yea that price is a lot to swallow at first.

 

The 80hp gain depends on your pump settings, turbo, intake, exhaust, ect. A mostly stock truck, stock intake, stock exhaust will see a smokey 70-80hp gain. A truck like mine with a cranked up pump, exhaust, intake, and other mods will see closer to 100whp gain. I originaly was thinking about 370's because they were much cheaper, but smoke alot more and are not quite as effecient. I finaly went with the DDP because I'm not a big fan of smoke shows and poor mileage. I was just hoping the DDP injectors ran as clean as the stock ones did, I was pleasantly surprised when they actualy ran cleaner. No more puffs of smoke when I shift gear to gear.

 

You didn't have those in when you dynoed your truck did you pwrtripls1 ? Your numbers look low in your sig

 

The numbers in his sig were back when he first got the truck, before the injectors.
