How does this look...log file

[LS1IMPULSE]

I just got the car running again after a new round of mods so I hooked up the HPT and got a data log from just an idle and little up to about 2500-3K RPM. Just wondering how it looks to the people on here who know much more than I do.

The car still has a bit of a problem searching for an idle, it dips about 100 RPM consantly and goes as low as 700 and high as about 1100. Also, how do I tune the fuel trims, they go to -25 points. Is there anything else wrong with this, and how do I fix it up. I am considering going to Rapid Motorsports for a dyno tune, since I am not sure I know enough to tune it without causing any damage that I cant afford to fix, but I need the car to atleast be able to make the hour+ trip to get there so any help would be appreciated.

Tune added.

I modded your VE tables Primary & 2ndary as things were a little lean..
I also put you in VE mode and copied your HO Spark to LO spark.
Last but not least I turned off your LTFT's.

[LS1IMPULSE]

whats the benefit of turning the LTFT's off?
