hello there. we are always honest with people always do the best job for your money and never cut corners.and we never quote silly power figs for engine spec.out of al the hundreds of customers weve had im sure theres probably 1 or 2 that arent happy but then theres no helping some people.as for saying my bros mate wasnt happy so i wouldnt go there well you should always atleast check something out for yourself then make your own mind up. cheers
