Problem: Every time I try to give 100% throttle to the car, it doesnt accelerate harder throughout the powerband, it just "bogs" out. This makes it useless to floor the car. I have always had to baby the pedal and rarely go past 50%.

I am using the SAFC-II, my car was just dyno tunned, but I dont think it was done properly. I really need help from someone who is familular with tunning the SAFC w/ 2JZ's. I just have a few questions.

Where should my TH POINTS be?
Mine are set @ LOW 52% HIGH 80%

My HI THROTTLE from 3400RPM to 7000RPM is at +17% all accross.

My LO THROTTLE is pretty much zeroed out.

This is what I was left with after the tunning session. J-SPec 2JZ-GTE Engine mods HKS Intake, HKS Exhaust, GReddy BCC, Apexi SAFCII. Stock Twins.

that is wierd that it is +17 all the way across.

I do not have a 2jz but i do have a 7mgte. When we were tuning mine. We put throttle at 10% and high at 50%. It may be different for 2j's but the stock computer controls all fuel until 75% throttle. We kept my low throttle zero'd out as well since i was still on stock injectors at the time.
The only way to tell if you have the same a/f ration across the board is with a wideband.

Also if you havent turned up the boost yet....you would probobly be running rich since the turbos are on stock psi. That may cause it.

My guess

you are probably knocking and the car is pulling timing. That would make it feel like it is bogging down.

adding 17% is a lot of fuel to be correcting for. i agree with figgie.
