I got a K.L.S power spirit FMIC, I will try leave it running after i reset it, I didnt really thrash it after i reset it this afternoon, the problem i am having is that when i acelerate, it seems to lag a bit , and then judders and seems to misfire just a little bit, then goes, it feels like it wants to take off but something is holding it back, do you think it could be because of the std fuel pump? I'm planning on putting in a walbro 255 and fuel reg. are those worthwhile? someone insisted that i get a Bosch 550 but I dont think I need something that serious for now. So to date I have just put in the FMIC, superflow HKS and putting in the GREDDY profec BC this week sometime. I know this may sound stupid but what are coilovers for and do i need to get splitfire ones? sorry, I really dont know much about skylines but am learning so much from this forum. Thanks so much for all the responses, I will have to reset again and try what you guys have said. Much appreciated
