Default Blow through LQ4 tuning help

As it states I'm looking for some help with getting started on a tune for my blow through 6.0. As I've been reading over and over, the tune is key. Bad tune is gonna end in a bad time as I so dreadfully experienced last week. $1500 and 2 weeks later I'm back and running but im deathly afraid to repeat this disaster and want to make sure I get this as close as I can. Sending it out is not an option, with a little help from some experience I'm sure I can get the hang of it. This is what's in the truck now.


Current tuneaytona Sensors ignition

Truck is a 93 S10 with a 2002 LQ4 with stock lower end, stage 2 tick cam kit, 76mm turbo, 750cfm dp CSU blow through, Daytona Sensors ignition running 12psi all on e85. Engine seemed to run pretty good but I'm just learning and absolutely know there is room for improvement. Any help or knowledge is gradually appreciated

Looks pretty safe as a starting point. Do you have a wide band 02 sensor setup ? If not would recommend getting one.

Yes wide bands installed and on gas scale. Haven't got carb dialed in good enough yet, still too rich under acceleration. Af reads around 13.2-13.6 at idle, 11.5 cruising with big toe on pedal and drops to low 9's on takeoff anytime. Any pointers or tips when I'm mapping the curve?
