1015hp, with version 1.6b. This is a new best for my truck. The best before was 925hp, so a really good gain. This is going to be a long post, so bare with me.
First thanks to Marco and everyone at Source Automotive. I got the pleasure of being able to spend the week at Source Automotive while Marco was there. It was a once in a life time learning experience.
When we started I had the version 1.6b installed with the same settings I had been using with 1.5b. Those settings were:
LLT = 24
LLD = 8
LLR = 1
HLT = 28
HLD = 30
HLR = 1
We used this for a base line pass and made 923hp. Very close to my previous best of 925hp. Marco suggested that I change my settings to the following:
LLT50
LLD50
LLR25
HLT50
HLD50
HLR25
This is what the graph looked like:
Marco looked at it and said that it looked like we were blowing the PRV open. I installed a rail cap, to fix that problem. The next dyno graph shows three runs. The first one shows with the rail cap and the above settings. You can see the "chop" in the run. The second run I decreased the timing to 45 on both the high and low. The third run we started the run a little soft (operator error), but I wanted to carry the rpm out farther. Here is the graph:
Just to verify that the high timings values were indeed what the engine liked, I lowered the HLT to 30, and LLT to 20. Here is what the run looked liked:
It ended up with a nice curve, but the power was down. I probably would never have tried that much timing on my own. I have a timing phobia... LOL
In all we made about 30 pulls on my truck most in the 900 to low 1000hp range. Not only is the hp up in my truck, but the power band is much wider. I ended up with settings that net me an AVERAGE hp of over 1000, in a power band that is about 700rpm wide. I can't wait to get it to the track for testing.
The settings I ended up with using version 1.6b are:
LLT = 45
LLD = 50
LLR = 25
HLT = 45
HLD = 50
HLR = 25
