just wondering if anyones tryed the accufab 75mm tb and plenum conbo.. i saw it on american muscle and it says 9 hp and 15lb/torque. sounds pretty good... does it make a real noticible difference (ihave an 01 gt with jlt ram air, magnaflow catbacks, 3.90s, plenum spacer,and a diablosport tune)

 

I have this combo and I would buy it again.I don't have any numbers for just these two parts alone though.
