OMG rebuilt tranny and tune feels perfect

Well might sound simple but I have been tuning my car for months thinking most problems were fuel air maybe some slip but after tranny leaks and slip still drives me I kept chasing AE and use tunes to give me power

I had my tranny pulled and torque converte failed and tranny leaked quarts daily. I had stage 2 rebuild and shift kit and acummlatit and 2k stall installed and the car Feels awesome!!!

Like althe car should feel like new almost. Idles fine great sound with straight pipe and flowmaster

Dead stop or 15mph roll the car smokes the tires and chirps second the pedal has great response

So my question I thunk I might tweak the AE. I am seeing some rich idle condition at idle and probably some light AE tip-in

My AE hits 3.98 3.77 1.75 1.5 1.25 1 0
So heavy fuel and from dead stop grabs hard but for general drive wonder if it is little rich and shift the hump more to the right and fade to 0 quicker? Any ideas

Oh stock 305 tpi Iroc
Also anyway to have 0-60 or dyno numbers from the Log file like the iPhone dyno apps?

Re: OMG rebuilt tranny and tune feels perfect

Update: Well I pulled some logs and I realized after my longest drive yet, a full commute to work about 30minutes in bumper traffic and up to 70mph. it ran and idled fine and had power but as it really warmed up at end of drive when I gave it gas or WOT it bogged like it was rich. temps seemed to hover at 199.

So the logs confirmed at MAF 1-2 tables up to 1000rpm it just goes rich like 118-120. but when colder, 186, but still closed loop it is 128 and feels much better.

I know my AE tables are peaked out in first few cells prior to tranny rebuild. this could be causing the tip in and light cruise bogs at low ranges.

But from the temp warm up condition is that maybe a temp enrichment table thing? I am thinking no since it appears to be just down low and maybe it was my lower MAF tables which i tweaked scalars up prior to fixes need to come back down.
