I must be the only guy not happy with making more power , I was hoping for less TQ so I wouldn`t have to pull the other drive guardian.lol
I had the drive guardians recalibrated to 925-950tq and now that I`m making almost 900tq it makes sense why I burned one up. Going to attempt to pull the other one in the boat so that should be fun. Setting them up for 1000tq . Do you have timing control now? You could pull some in the middle. |

Do they recommend tuning that close to your engine torque? I’m surprised the margin isn’t higher. Do you have timing control now? You could pull some in the middle. No it`s too close, that's what I`m saying I have to take em out and get then recalibrated to 1000tq, I based the calibration on 826tq which was the last tune up. Holley HP has full timing control . Wouldn`t be good to lower the timing to possibly send the EGTs thru the roof thou . |
Something that gets forgotten quite often is dyno pulls are done at wot. When cruising at 3500-4000 rpm your not at wot. So the numbers shown are not valid when cruising. Steady state tuning is very different than the power pulls. |
Nice numbers!!
What a/f are you running? |

So Dan, did y'all have to tweak the tune or is this what Alex sent you?

I think Alex said that tune was for a whipple deal so I added timing up high and fattened it up a bit more.
Most of the work was on the idle . That was a ***** , 2 days worth of tuning to get it to transition right between in/out of gear but at the end of that it idles like a dream at 850rpm and 13.5afrs . I had it out in 46* weather and she`d go in gear without dying with very little warm up. I`m running it in closed loop with compensation capped at 15% in case the 02 takes a dump. so far so good . |

Nice!!!
