Tuning?

[SlowWhite]

Ok just went for a ride and noticed something on my logs. Even at 30psi my lbs/min still are at 53lbs/min. So what's up? that's the same lbs/min I was seeing at 22psi.

But when I first started out on 23psi I noticed my lbs/min were 55lbs/min?

Maybe you maxed the MAS?

[niterydr]

I would also bet you were pinning the MAS. How many Hertz of airflow are you seeing? I think the 2g one can read up to 2800hz ? I'll have to go look it up.

GM MAFT it. ;)

Yup, time for a MAF, unless you wanna do MAP w/ EMS.

[SlowWhite]

That's sucks. For now till I move back I'll probably just keep pushing it on Pump Gas. And then go to MAF or EMS later.

Hopefully I'll be able to get a little bit better of a tune going should still be able to make more power even if I won't be able to up the boost to where I wanted it.

[Shane@DBPerformance]

You could start hacking the 2G MAF and using the MAF compensation table in DSMLink or just clamp the MAF and start using the VE table in DSMLink.

You need a PMS.

Well Not sure exactly if this was the problem but today I took the car to work, and everywhere that entailed. and no matter what I did the stuttering never stopped.

Well right as I was on my way home about 1/2 block from my driveway I got on it to pass a car and My downpipe coupler fell off. Not sure if that was the problem the entire time but I did lower my boost back down to 25psi which I'd been running on pump gas for ever. And still had the same problems. Plus I was noticing that my boost was coming on later.

I found the coupler (went home and jumped in the concorde with Jenny) and it only had minor scratch's on it from bouncing down the road at 45mph. I got lucky it bounced into the divider. so it didn't get run over.

Anyrated I'll start to put logs up hopefully later tonight for you guys to review.

The most boost I was hitting was 32psi and it was always fine till about 6000RPMS (which is just about when the boost was coming on really strong (typically I'm at full boost/spool by 5800rpms)

You probalby just found your air flow problem.
