I talked to Simon , as Simon of SECS and he told me he runs japanees injectors, 100£ each and a big T34 , runs 450HP!
He has done his own map ..... sounds like he knew what was good and what not.

it's alot cheeaper to go 4 injectors, they are 100£ each but you don't have to buy an 8 injector hardware.
