I just finished my 1jz swap into my 88 Supra. My mods include Wlabro fuel pump, GReddy profec type-s EBC, Airinix intake, HKS DP, 3 inch TP, and a nice HKS super dragger exhaust. I did all the mods before I did the swap, and I have to say, at about 3500 rpm's this thing really wakes up and keeps pulling hard. But I haven't used the ebc to up the boost, I just set it to stock 10psi. I'm wondering, what would be a good safe boost level to raise it to? I'm running stock twins and stock injectors. Thanx.
Raising the boost :)

I think if you use a 2jz map it will raise the cut. The map is what causes it to cut since it only read to 15 psi I do believe. THe other thing you could do is build your own FCD with some resistors.
Bascially you need to lower the voltage of the map
someone correct me if im wrong

only if you have a wideband so u know that your arent leaning it out too much. In my BPU car i ran safcII and with no changes i was 11.5:1 at 14 psi so leaning out would have been bad for my motor.

walbro installed, and every car is slightly different, If you are going to mess with the airflow signal get a wideband, end of story.

I think you should probably get a fuel cut defencer along with the AFC. Leaning out your car isn't always the safest thing to do. Keeping your car on the rich side of things keeps your engine cooler and safer. The AFC will be great for tuning, but it can be dangerous to your motor if you lean yourself out too much.
Don't be ghetto.
Get a fuel cut defencer. The SAFC is to CONTROL the fuel, not defeat boost cuts.

agreed. and u should go get a wideband. itll save u a motor in the long run. i kno first hand lol
I have a Greddy BCC with idiot proof wiring diagram I made for sale if you want it. PM me if your interested.
GEt A Greddy BCC if you want to raise boost. SAFC-II WILL NOT get rid of the boost cut like everyone is saying. The BCC will help you raise the boost, but make sure you have a tune done at the level of boost or have a wide band meter to help you monitor the afr.
