I did the bypass and then after a week or so it annoyed me, so just scrapped the N249 and N112 delete with the resistors and forge blanking plate and made a massive difference, bay looks much neater.
as for the fluttering, what size tubing did you use and have you cable tied them all on / checked them all ?

What annoyed you about the bypass  :undecided:?

I used 3-4mm & 5-6mm silicon pipe and all are clamped tight to the connectors!

Have you got a link to the N112 delete?  :smiley:

This is how mine is set up & I get nowhere near that amount of turbo flutter:

why did no-one remove the metal pipe??  :laugh:

do you leave the valves plugged in so there are no codes that come up??

i've binned the lot and have resistors in with no codes,i still have metal plate in that the 249/112 should be on the back of as i used it to hold my catchcan

10w 330OHM resistors the ones with the heatsinks soldered 2 bits of wire 1 each end,then got some male connectors and cut them to fit the holes,then covered them in electrical tape

Should I be getting any flutter atall then :)?

How you've routed yours have you left the plugs in the valves or did you put resistors in?
Cheers

I have a pipe from inlet to dv,the other one from inlet to fpr and a t piece on that to boost gauge the 249,112 and all sai gubbins are in a box in the shed.I used 2 resistors for 249,112 but none needed for sai as you get the improper flow code either way.if your removing sai you will need a blanking plate for where the combi valve is
