440's on 1jz

[mk3tattoos]

Is there any gain to putting on the 440's, or should I just wait unti I go single?

I know if I want to raise the boost I would want to install the 440's, I am running off the stock waste gate and with the free flowing exhaust that I have it is hitting 15psi at 3500 rpm's.

So by pulling alittle fuel out and keeping A/F's at 11.5 through out the rpm's I do not hit boost cut.

If I install the 440's I was thinking that I might screw up my tune and hit boost cut, what do you guys think? Mods are down below.

Well you wont screw it up You'll just add more timing. Try to stay in the -10% range. If youre fine now and wont turn the boost up I wouldnt even bother.

That's what I was thinking. I'm not turning up the boost until I get the 60-1 kit from DM in the middle of summer.
Car is pulling very well with the few mods I have and I'm happy for now loving the mines tuned ecu!!!!
