Hello Guys, last Friday when I picked up my engine, I had a 6L waiting for me on the dyno to tune. It's a completely stock engine with no mods, right out of the crate.
This engine put out 311HP and 351TQ on the first pull.
I wanted to see what timing did as it was increased:
Stock - 14-16degs : 311hp/351tq
Tuned- 20 degs : 350hp/380tq
Tuned- 25 degs : 356hp/390tq
Tuned- 30 degs : 357hp/392tq
Fully tuned with a/f ratio and max timing of 31 degs:
367HP/401TQ
Gains: 56HP/50TQ
There might have been a few more ponies left if we leaned it out just a few more points, but their wide-band wasn't working right.
Next time: stock 6.0L with 224/228cam and
FAST intake vs Truck intake.
btw just an fyi, the last 6L I tuned down there was an LQ9 that put out 441hp with a 224 cam, I was mistaken, I told you guys it was an LQ4.
later,
allen
