Getting a feel for what is required for stage 2+ as stage 2 doesn't seem worth it over stage 1, especially when you look at the power graphs from revo for the different stages and the difference in hardware between them. So for me I think it will either leave at stage 1 with a milltek cat back or go to 2+ with a TBE, HPFP and CAI. Looks like the options for the fuel pump are to either buy the internals (Â£400 (autotech) to Â£475 (APR)) and upgrade your existing pump or buy an upgraded unit for Â£700-Â£800. Upgrading the pump doesn't look too complicated (seen a thorough step by step), although AmD will supply and fit for Â£600, including remapping to suit - however I assume this is only for people with at least AmD stage 1. My car will have Revo stage 1 from the dealer (Fontain are a Revo dealer, so got them to include a stage 1 in the deal). Anyone know how much a stock fuel pump costs? Would consider buying one to upgrade, so I can revert to stock more easily. Any other options? Trawling the second hand market for as many parts as possible!
