Title: Fitted a K04 hybrid on AGU now over boosting to hell
Post by: gti_shaun on 04 September 2014, 21:49
Hi all, Ive got a hybrid K04 fitted and I'm getting it mapped next week, took it for a little drive to bead brakes in as they are all new and booted it just to see what boost level was, I won't be doing again as it went off my guage (over 2 bar) needles to say it span both wheel on third gear(LSD)

My question is, could this be some thing I may have done even though I'm positive the n75 is piped up correct as I marked it up, the actuator has a 3 turn preload, or will this be turned down on the map, I remember nick@ rtech saying he left a aggressive map on from when I was having boost issues with my old turbo, could it be in the map, as obviously a k03s can only boost 1.6 bar max so it wasn't going to Super boost....

I will test the actuator tomorrow with the mity vac and make sure the diaphragm isn't bolloxed

Not true, when I was having issues my K03s boosted over 1.7 bar

if it has a 1bar actuator like most k04 hybrids i've seen, i'd say that's normal behaviour with an aggressive map written for a k03s. unplug the n75 and stay off boost until its mapped to suit the new turbo

Thanks for the replys, Ben from rtech rang me today and said the same thing, wish I gone all the way and done rods and everything now because I love the 2+bar ha ha

Def need rods with k04 hydrid like half a job if rods not done and won't get full potential from it when mapped. What k04 hybrid you got??
