I’m tuning my 87 Camaro TPI using ABWN bin(160 ECM) with TunerCat. On take off, under acceleration the engine goes way up lean and then comes down. AFR goes up to 18 and then back down to around 12 in couple of seconds.
What can I do to keep the AFR down?
I think it has to do with some kind of PE
What table should I change and Why?

Thanks,

 

The ECM is 165.
