is my turbo too small Options

[RUNNIN-LOW]

well ive ask this once i think already but is my turbo to small. i have a t-25 and yeah it smaller then a t3 also im boosting 7psi. but i feel no boost on high gear. just first and second. the weired thing is that i cant even pill out on 2nd. WHAT SHOULD I DO!!should i just add abigger turbo.ive been asking around and have sources to get a ct26 but im still thinking that i might have some power hidden in my t-25

almost all the T3 series is too small for the 5s. IMO if money wasnt an object, i'd go for a T3/To4E hybrid with a 46trim compressor and a .48a/r for the turbine.

in that graph i plotted for 7 and 10 psi...good stuff, and as you turn up the boost it just gets better. i'd definetly sacrifice a little spool time for what that turbo will give ya
::EDIT::: heres a plot of a 60trim T3, just so you guys can see what im talking about, this is the largest compressor in the T3 series.:

as you can see, your almost off the right side in the higher RPMS...anything smaller than a 60 trim T3 and your way off the map by 4500-5k...the exact reason your car falls on its face in the upper rpms, with ubber quick spool, your turbo is too small.
IMO if your going to use a T3 nik is right, go for the 60 trim

there are 60 trim and super 60 trims but i would agree with pressure i would go t3t4 if you can afford it. If you ever wanted to beef up the internals down the road the t3t4 will still work as the t3 60 trim would start to see its limits.
