What size slicks do you guys recommend for 14+ psi of boost?
I was thinking 24.5x8x13 or 24.5x7x13.

 

22x8x13 should be enough

 

i got 22x8x15 and imfine. . . . im pushing about 250 to the wheels right now.

 

Go with 24.5 x 8 x 13. 22's will be ok but it will still spin in 2nd and 3rd

 

With 24's get ready to shatter the stock diff. 22's should be good with the stock diff. If you got a prodrive or quiffe then you are good to go 24's. 22's wont spin all of second if you know how to drive.
