The L trims b1 were mostly in the 7's and L trims b2 were mostly in the 9's. Not really sure what to do with this. I was seeing up to 8.5 lbs of boost around 6000rpm. constructive opinions and advice would be appreciated.. Thanks Jason

I know that they are kinda hard to cipher.. wish I knew how to put them on here better but I could sure use some advice right about now.. thanks Jason

 

Ouch! Too Lean!!

ok, easier to read like that <img src="gr_stretch.gif" border="0">

first question, stock tune?

sencond question, injectors??

MAF numbers might be nice too, and maybe gear.

The O2's aren't actually that bad. I run 890'ish and i'm wideband tuned for 12:1. so it's not that "lean"

Was this on pump gas??

judging by the timing numbers, and KR, and at 8 psi you need either 2 degress out at the RPM/load where the KR initiall starts. Or you need to run more octane.

 

Thanks Harlan I appreciate you re-writing them for me.. How in he!! did you do that?!!!
"STOCK TUNE?" Superchips programming
"Injectors?" 38's with in-line pump
"MAF #'s and Gear" running the stock maf with 3:73 gears,(Don't know if that will help ya)
I am running 93 octane pump gas.. Again thanks for the help.. Jason

 

I vote for too lean. My o2s showed .925 when tuned to 12:1 showing you how they fluctuate from car to car. I'd try to richen it a tick with a maft or bump up the fuel pressure just a tick and see if the KR goes away. If neither of those options are readily available, you may want to try and reverse your maf as that has richened things up for some people. I wouldnt leave the maf like that forever....just try it and see if thats the problem. If not then you need more octane or less timing. When you get down to 1/4 tank, get a gallon of Xylene from the paint store and try that in the tank. Will cost you about 6 bux

I do have a MAFT I will try richening it up a tick, and see if that cleans things up.. It seems that I am already running pretty low #'s as far as timing is concerned.. But I am no expert at this point. Still in the big learning curve.. What kinda timing do the rest of ya'll see at wot? Also are my Ltrims anything to be concerned about? Again thank you, Jason

 

We are making the same power and I'm running 24 degrees of timing with 100 octane. I think I could run 93 octane if I dropped my timing to 16 like yours. I think you are just right on timing tho...at least not too high...maybe a little conservative.
