Just finished installing another STS. This one is on a 1/2 ton Chevy, 4X4, 5.3 with shorty headers & underdrive pulley. We did STS with 60-1, converted to LS1 style injectors and put 60s in, installed intank Walbro pump, designed a fmic kit instead of using STS', BOV, wideband O2 and digital boost gauge. Allen sent us the tune.






The customer is planning a trip to let Allen tune in person to get the full potential out of it.

We did duplicate the intercooler kit for someone that doesnt like the STS kit. This one doesnt hang down and is only $800.00 for the kit.
