Boost Fluctuation after stage 2 remap

Postby wopwopwallace » Wed Jan 29, 2020 2:14 pm

Hi Rocco fans,

this is my first post on here and sure this topic has been covered a mutitude of times but I cant seem to find the answers im looking for.. I have just put a stage 2 quantam map on my rocco r. full system turbo back ram air induction kit and gfb diverter upgrade. since remapping i am not acheiving full boost unti 35-4000rpm, where befor it was 25-3000rpm. Also, when on WOT in 5th 6th befor boost builds i can hear the turbo stuttering slightly as it starts to build and im getting boost fluctuation e.g, 20psi-15psi 15psi 20psi and so on. I changed the DV on monday hoping this cured the issue but its the same.

Im thinking now faulty N75 or boost leak.

Have it booked in on tuesday to get vagcom'd on the rollers

Anyone any ideas, thanks in advance.

What version DV did you change to? Plastic internals or Rubber one?

Id look at changing the N75 valve once your sure its not the DV or a boost leak

I went for the GFB DV+ mate, changes trhe stock internals for billet one's,

Im hoping its an easy fix, feels like a boost leak as its taking the turbo bout 1000 rpm more to reach full boost. failing that new N75. pissing me righ off like hahaha

Get a garage to do a smoke test. probably easiest way to detect a leak.

So, the map was the issue, no boost leaks or faulty parts. all fixed running a tasty 343bhp and 321lbs of torque. its ace

So Update, its back to the same issue, had it flashed back to standard, okay again. Do go for a generic map, they are pish
