Hi, in my FD i have single T78 GARRETT is T04 base .70 and .98 a/r. ( 4" in comp and for the hot side 3" ex )
My engine is stock port, intercooler same size PFS, 3" exaust pipe, PFS computer and profect B.
My question is : is normal in first gear the boost is not higher than 12Lbs.
For all other gear no problem to run 18 and more.
What do you thing?
Thanks

 

yes

 

with a stock port yes it's normal

 

Now i understand, with my half bridge i break seal at more than 20Lbs in first gear.
With small street port is possible to push 16Lbs in first gear?
Or i need big street port?
