The sirrio Dennis done for me was modded after he quit doing general public work. He doe'snt like the sirrio engines I don't think. He done 2 for me I think just for a anti Trinity thingy! I think I have the only Sirrio/ Richey mods. And after alittle testing with it against the Murnan power, Dennis still rules for the power range we need. Not cutting on Murnan, he does good work, but just not the power range we need. I'm also using a MT that has some Top Gun 777 work for short tracks that is very impressive to. Hell , the MT will eat the Rody RB 5 port turbos up!!!
Sometimes it pays to be more than the general public.
