My dyno readout
So never thought to post this up cus I forgot I had it. Let me know what you guys think. One of my friends said he talked to the guy who tunned my car and wasn't impressed with his knowledge so I hope everything looks ok. 2860RS, 440 RC injectors, MSPNP: 9697, s4 kit from bell with the middle sized intercooler

no MBC on your wastegate line is there? or .86 A/R?
moved to dyno section. |
How much boost? Could post a log too showing AFRs, around 4500 looks a bit lean.
I hope thats not higher than 13 psi on the 2860.... |
His sig says 10psi, and IMO 12's are a little lean for my liking
|
AFR's are kinda a fail, they look sloppy, plus it looks like the out of boost is super rich

.60 a/r and boost is controled by turning a nut on the wastegate arm. hope thats what you wanted.

Why do you say no MBC? Something indicative of such on the graph?

I suppose that the MBC comment is about the slowly steadily rising torque. Mayhaps indicative of a slowly opening wg.
|
I would work on the fuel map a little.
Looks like you hit nearly 13:1 ! AFR right as you come into max torque range. This won't help the big number, but may help keep from ventilating block. Spark map must be pretty aggressive though...looks like great numbers for 10psi. BEGi S4 ftw. |

I think they look sloppy but not terribly lean, the transition into boost is really terrible |
12:1 is too lean IMO, at least the Tq curve looks smooth
