The guy said my Afr was crazy low, I could get another 10hp if I retune. The second and third run were below 10:1. The wideband didn't read below that. I was datalogging all the runs.

 

[CheapFuneral]

Yeah.

 

[ScarabEpic22]

Yea...that tune needs work. If some shop tells John this tune is fine, all anyone else needs to do is look at this graph to realize that is NOT the case. I could even write off the initial lean part due to the sniffer being at the tailpipe not right after the turbo, but 10.7:1 is waay right even for a port injected, boosted engine.

dat TQ curve do....and 29psi!

Prob 10hp and some TQ left on the table with that much extra fuel, choking the engine out at that point.

[Kuntryboy865]

Im sure it is seeing how you know this from a little spirited driving we've done in each case i never got on it enough for you to really know. Why would i floor it on roads i dont know?

 

[krakenredbeard]

I have never said I think you would lose. I have always said I think it will be close.

I just want to see it.

 

[brasschucker357]

I'm not going to say that I think I'll win, but I think it'll be close either way. I'm just curious, mostly.
