I want to go Stage 1 but I think my mods may be a bit much for it. The main one is my H-Dev S/S exhaust mani. Would this really make such a big difference? I can swap over with the cast iron one, but want to avoid it if possible. I spoke to Jez and he said id be better with either 2a or a custom map, but i cant afford 555cc injectors or the £399 for a custom board, especially just to run 15psi.
Who's running Stage 1 and what are your mods? I know it states on the H-Dev website but its a tad vague. Cheers guys
