will this not effect performance putting standard back on? what induction kit wud be best to go with it if i was to buy new 1
if how ever, it occurs when cold and eventually like after 5mins driving it boosts normally then many people have issues like this
the n 75 boost valve are they expensive?
I thought i read somwhere this is normal for it not to boost stright away when cold? some sort of safety feature for the engine?
David.
My boost wont seem to go over 6-7 psi and seems to please itself. I replaced my MAF and it made a little difference as well as my MAP sensor. I noticed a valve that has 3 rubber hoses going into it and an electrically plug, one of the hoses goes to the turbo actuator and one into the air intake pipe behind the MAF. I took this unit out and put in a plastic T piece and joined all the hoses to the T piece it seems to run loads better but still only 6-7 psi boost max. Have i bypassed the N75 valve?? my engine is in a VW Caddy pick-up truck and has no N249 valve (i think) or one of those air pump valves as it has no cats. Have i bypassed the N75 and is it a wrong thing to do?im In nottingham m8 but every week i go london (hendon) to! busy boy! Is the n75 boost valve near the recirc valve! it only goes to 5psi the odd time some times when warm some when cold
i have the reciept where the guy had his dyno tests from would they have remapped?
Will do cheers mate.i got a spare N75 if you wanna buy it off me for 70 quid. lol.
No offence mate, we dont know what map you have so we cant really tell you what boost its supposed to be running, best bet is to find someone local to you who can vag com it.
Changed my N75 today J and it runs wicked again. Boost is at 1.5 max but a steady 1.0does it only go into limp mode if you've revved it hard?
my car sometimes does the same if I take it to c. 6k revs in 3rd. I just flick the ignition on and off on the move and its fine again.
mine isn't maf related because it did it before and after i changed mafs last year.
