Just had this car from Jord, bought it with KO4 setup (turbo injectors fuel pump MAF etc.) with custom downpipe, full milltek decat, but no FMIC, just a standard SMIC, (i knew i would need to invest in FMIC to run 275bhp as quoted) car has been stage 3 mapped custom code.
Came across my mate who got an Ibiza 2000 plate, KO3 turbo, but been mapped and has had most parts changed in the engine, bar the turbo, and he got a RR printout of 240bhp at the fly, 260 torque. So we had a little play, but he was pulling on me through all the gears. Granted, its a lighter car, and i had an extra person in my car, and i'm on bigger heavier wheels etc, but would a non existent FMIC really cause such a loss of power? 35/40/45bhp? what would your first port of call be to get back up to the 275bhp ish, other than a FMIC - if i t needs anything else? I'm going to get it RR'd to see what figures i get back so i know exactly how much its losing.
And i thought the general consensus was that KO3 turbo runs out of steam at 220bhp (at a push) and you cant really get anywhere above that?
