I've been driving my truck set up as you read in my sig. I just took out the DennyT pin and turned the pump down just a hair because it's idling a little high from when I put my 366 sping in last Dec. I guess I turned the pump up just a tad on accident, oh well.
I'll tell you what! The truck feels sooooo slow now it's actually kind of aggravating.
In case you're wondering why I've done such a proposterous thing, I'm getting the truck on a dyno this weekend and want to know baseline numbers. Then I'm throwing my DDP 80 horse injectors in and doing another dyno and then putting my DennyT pin in and doing one more dyno. Then we will see just how much power those 2 mods actually add!

After this weekend next on the list of mods is going to likely be the turbo upgrade from GDS. After that is possibly tranny work/fuel delivery/fuel screw. We'll see what money permits over the next few months.

If all goes according to plan, you will all hear back from me on how things go!

 

haha i still remember what my truck was like stock, sooo slow. good luck with your dyno day.

 

Yeah thanks!

I forgot how sluggist it was until today... yikes it's slow!

However, I'm excited to get some baseline numbers Sat. and to see what the numbers are with my DennyT pin and then injectors.
Now we'll get some definitive hp ratings over a stock pin in a mostly stock truck to a DennyT pin. Speaking of that... I slightly modified my DennyT pin actually. It seems it was not sliding back fully (which might half explain my somewhat crappy fuel mileage because the pin was always half way down the cone, it wasn't returning all the way because it was binding) so I ground my DennyT pin a bit. I lessened the angle a little at the top of the slope and ground just a touch into the base and then buffed it with the dremel. So technically it should add a little more power over a "stock" DennyT pin but also return a little farther up the slope. If any of that makes sense at all...

 

I'll be watching this thread carefully to see what you find!

 

I got the truck done on the dyno yesterday. I will post the results later tonight when I actually get some time!

Here we go, finally posted my results!
