lol... wasn't directed at you man.... but.... hahahaa
thanks man. there is definitely more left in her, just need a better BC and a new turbo....
thanks man, it's hasn't been an easy ride, but I think I got her pretty dialed in, just one little rich issue down low I need to clean up, just really haven't had the time.

That's what happens when you get a shitty knock off ebay turbo. I bet when Paul gets a real good turbo, his tuning issues and little quirks will be all worked out. R&D, gotta love it! 
Paul, what are your plans for the IDC's? If you got the RKSport fuel pressure regulator, you could kick the pressure up to lower the IDC's. Just a thought.

look at the logs. the injectors are done. 20+ ms. ouch. so. in "theory" the pump itself is done at what. 330 fwhp? which inturn causes the injectors to go close to static. or is it the fact that paul is commanding 10.8, but running 12.0 afr. still doesn't make sense to me. one of three things. the pump is done, the maf is skewed something fierce, or there is a booger in the fuel map somewhere?
two round things with these cute widdle bumps on them
log fuel pressure perhaps?

Paul put out 356 whp at 6000 rpms on 22 psi 18 degrees of timing today. I don't know his tq but it was 307 tq on his 246whp pull His boost controller wouldn't hold anything over 22 psi so that what he worked with. He has vids and stuff he'll post later. He's still on stock clutch too so i really don't know what some of these other guys are complaining about.....
356/315 today uncorrected woot. vids loading up soon.
sorta fixed the fueling problem, well at least it didn't lean out.
1st pull 343/307
turbo cobalt, 1st pull of the day @21psi
2nd pull 347/311
2nd pull 22 psi 347whp 311wtq.
3rd pull 356/315
3rd pull, couldn't get it to boost higher than 22.35psi due to the boost controller.

I saw the dyno screen. you pulled 356 early on then torque and HP fell off from there. you think it is due to just the fueling or just turbo or combination of problems?
Good work. hopefully you can build it up to do even more in the higher RPM band.

But fuel is definitely an issue. from my readings my maf tables are spot on, so I'm pretty sure it's a delivery problem, also I really should change the fuel filter since it's the original one lol.
and for the injectors, when it's cold they hit 25+ ms and over 143% IDC. so I need to find a solution, and soon... also according to my maf and VE readings I had this turbo maxed out at 54.84 lb/min of airflow, so I guess it's time for something bigger.... and better of course.
