my boost will start kick in around 3k rpm, still abit lagging lar,but my previous turbine tdo4hl(rvr)much better,no lag and very active turbine,can hantam in any rpm,and the boost will come at any point of rpm!
oh ya...infinite intercooler definitely the right choice lar!even if u're using stock gsr engine,juz make sure the intercooler piping is around 2inch,it should be ok!
