Ryan has it and it takes for ever to Spool...I told AMARILLO 6.0 in a Pm anything bigger than a VGT-ss I would go Nonvgt....Ive done a ton of trucks with 190's and a VGT-ss or equvilant and they all tow well. I would only go to 200+cc's if your going to spray on that charger.
Plus if you going to tow the HO doesnt spool fast enough. I talked to Ryan on WEdnesday and he said Tadd wants his HO back and they are switching the exhaust wheel and housing..I think Tadd wants his to test another combo. He also has a blow off valve to relieve the strain on the turbo when he lets off the pedal
