Our 2nd best selling LGT OBXT unit!  It is great on the stock fuel system as long as it is tuned and boost stays below  13-14 psi (estimated 260-290 awhp).  There is room to go up to 430 awhp with upgraded fuel injectors and fuel pump.  Most customers target 350 awhp and the 18G performs perfectly for their application.  Full boost is around 3200 rpm with a very streetable power band, without the drastic boost fall off in the upper rpms that the vf40-46-52 turbochargers have!  The internal wastegate on the 18g is set at 14 psi crack pressure and is easily adjusted on the car with the double jam nut wastegate rod end.
