Message I Went to my friend shop and jumped on the Dyno to check out my AFR. My MPG where really bad ( 9mpg) and 1 of my wide band was read a whole point higher than the other.

We put the dyno's wideband in each pipe and they showed that both side where reading about the same. When I calibrated the wideband I did them both at the same time in the same spot. (Maybe because one is 2000 mile old and the other is new :-/)
Anyway the first run the afr dipped down so low that the Dyno could not read it. But my wideband read 9.5. I have Nistune im not a tuner and will not try to really tune my car but I know a few basics. So I lowered the latency and the injector multiplier and did another run. Hit 10.2 , lowered it abit more and got to 10.8-11.2 at this point I felt it I would leave it like this until I get it professionally tuned on the 18th.

The first run to 6800RPM @ 7 psi I got 298 RWHP this was after 10 runs and he only had one fan/blower so I pointed that at the radiator. And at 7psi I doubt the inter-coolers got to warm.

After figuring out the boost controller, I got the boost up to 8psi and we got 332 RWHP.

I stopped there, Im not that anxious to raise the boost on a untuned car. The afr stayed around 10.8-11.2.

I wish I was better with nistune and I would have went into the other parameters, but i'll wait until the 18th I will post up numbers, vid and charts
