without a front mount intercooler I wouldn't go over 8-10psi. but you also have to be weary of your s-afc settings.... and not run lean.

with A FMIC and some good tunning you would have a VERY fast car.

I have the old safc with ***** and they are currently all set just below 0. If I give it more boost I should also give it more gas correct? as much info as you could give would be the best!
Thanks!!!!

Also on the avcr it is reading 1.00 what rating is that and if I adjust it up what should it be?
thanks!

it's probably in bar. 1 bar is 14.7 psi...

Well if that is true then shouldnt my gauge be reading alot higher than 6 psi??? I am really confused??

First 1kg/cm2 us 14.7psi.

What gauge are you reading 6psi??

Your are in a dangerous place.

Last year I went to .9, I blew my engine allmost instantly but I didn't have bigger secondarys.

What is your duty cycle set to? What are you settings for boost A and B.

You should be able to control your boost if you have an adequate wastegate. Who rebuilt your turbo?

Other then that you have a nice mod list.

My car boosts to .85 before I have to back off or at least 12psi. I have a VSPL Greddy FMIC but just a remapped ECU and 3rd gen fuel pump. No other fuel mods.

I am reading my autometer gauge in my pillar!
Also I dont know how so set my duty cycle or what to even set it to! That is why I had this post.
My A setting reads 1.30 and my B setting reads 1.00
I think that is in the mm/hg though

1.3 is like 19psi.


Who set up you AVC-R.

I'm no expert but that sounds like your going to pop your motor..

The duty cycles is set under settings. To much slow response and less boost. To much you get spike or creep.

While setting parameters under A press Right arrow to see settings under boost settings.
