Hi i just dynoed my truck last night on a dyno jet in california on 91 octane and some booster..


the first run is my street the second is race..what i need ot know is what to tell JDm my current set up is filter.90mm maf, 4lb, catback, t.b i want a little more power and a little safer as they said i was running dangeriously lean... Also it detonates down low on load. thanks for everyones replys

 

Nah.

 

Before 4200 RPM you are very lean. Now the question is: Were you at full throttle at 3800? If so, get you tune adjusted quick.

You can probably lean out the top end a bit, but the bottom end looks dangerous.

 

Full throttle was at 3500.. it would downshift below that scared the crap outa the dyno guy when he kicked down into second and the whole truck jumped haha

 

I'd email JDM your dyno sheet and call him.....................
