Hello guys, I was used the Tial QR witl 12 psi spring in my Evo for long time, so my question is, there will be a difference in tune and performance if I install a brand new Tial Q? The blow off that I use is vent to atmosphera so thats not a problem. I plan to install the same 12 psi spring in the new tial Q. Whhat do you think?

 

Shouldn't be a problem. Why do you VTA instead of recirculate?

 

I bought the Tial QR because I used before a FP Black turbo and made it recirc. When I changed to 6266 turbo I used vent to atmosphera.

 

turbo has nothing to do with it. if you're running a MAF you should be recirc, if you're SD you can do either

 

I use MAF but I have the QR to atmosphera and no problem at all.

 

With your turbo setup I'm guessing you're tuned. You can run vta with a maf no problem as long as it is adjusted for.

 

You should be running speed density...

 

Yes, my engine works great and its tuned (with stock maf). Idle its fine, all its fine. I only want to know if I instlall the Tial Q my engine will pull normally? theres will some difference?
