is this a chassis dyno or engine dyno? |
chassis dyno with a 4l60e with a 3500 vig stall not locked |
I knew you were down on power. Looks like a tune could solve it though. |
ya im loosing thur converter a lot id prob only gain 10hp |
Seems low to me. Are you just stating the #'s or are you asking why they're low? |

Borla 3" exhaust Accell Super Coil FMS 30lbs. Injectors PI VIG 3500 Stall Converter |
Get a 6AL to only pull timing when you spray, leave that 4 degrees in there normally. Were you lifting on the dyno at 5800 or does it legit just faceplant like that? That cam should want to rev past 6500. |
Disregard what that power number was, too many variables with dyno types and settings, and you have an unlocked stall which eats a lot of power anyway. Besides your tune being way off (that A/F on motor looks terrible), something else is strange. With the 987 springs and that cam with ported heads you should be pulling way past 5800. Doesn't quite look like valve float or ignition problems either. Do you have a data log with your knock counts? |

I had a hand held scanner my knockcounts were only 17 in fifteen minutes of run time that's getting on it a few times never detected knock |
ya its rich on motor but the plugs seem to be good. another variable who knows when his o2 sensor was last tested |
Get that ARF leaned out and you will see some gains. Probably pickup some MPG too. |
