Yes it does.
I do use the block heater here in Phoenix when it's cold and I know I'm going to be driving the truck.

rdnckhaus, sent you a PM.

94cummins12v,
ON A STOCK TRUCK, The Grid Delete delivered 15-18 lb/ft and about 6HP from 1900-2000rpm, and from 2100-2200 it made 20-25 lb/ft and around 10HP. Power then is about the same as stock through 2500 with another increase around 2650rpm of 9 lb/ft and 5HP over the stock heater grid.

On a heavily modified truck, gains in the 17 HP range have been recorded.

Here's a link to the shop that did the dyno runs if you are interested in reading a little more about it.

One thing I failed to mention in the article, is when starting a vehicle with the HGD in place, do not wait for the pigtail, or "wait to start" light to go out before starting your vehicle. Doing so will throw a code. Just ignore it and crank it up right after putting the key in.

Also, this may be a way of confirming you live in a warm enough climate to keep the HGD on year round. Our winter lows here in Phoenix are usually mid 40's, with a few days of exception, if that helps.

As stated before, it may not be the mod for the colder climates...

Default Grid Heater Delete

Can anyone tell me about the #1 injector line rubbing on a grid heater delete block? I've got one on order and am concerned that this will damage the injector line.
Thanks in advance.

Pretty simple story.

First, some manufacturers mill a clearance area out for this.

Install your HGD... DON'T panic!! !
If it is touching, or rubbing, carefully pry it away from the HGD block. You only need it NOT to touch! So, don't get carried away...

I used a screwdriver for this.. Primitive, I know, but sometimes, the simple solutions work the best.

Over thinking some stuff serve NO purpose but to tie you up in the Minutia.
