Hello I am looking for any help I can get with this. Its a 3rd gear pull that needs tweaking of A/F. I am curious if anyone can help I am just looking to smooth this out as I have to move in 2 weeks and all the dyno places have lead time of months and cannot help at this time. Im just looking to drive it without any issues to the engine not a performance tune.

I attempted to fix your a/f ratio, smoothed out your low / high speed table a bit hope it does the charm for ya.

(Few things looked a little wonky to me but I am new to the tuning world.)

Thank you very much hoffmvn, ill load it and hopefully that helps. Ive been trying to fix it the last couple days and its been getting a lot better. I wish I would have looked sooner. Here is the last kal I have where the start up wasn't too bad, still lean close to wot but drivability was a lot better

The adjusted kal helped a lot but I still have a stumble upon start up. A few more adjustments and should be good.
This is an 06'-08' stock engine
custom cold air intake to fit the stock intake manifold
k20a2 exhaust manifold
no IACV
