They do it by design if im not mistaken. So you dont veer onto oncoming traffic when you're having a mid-drive kip
All the PCV hoses under the inlet manifold are the usual places for a leak. I'd start there.Yeah have the boost gauge. Seems to be jittering when idle, boosts sometimes holds at 10psi then will hold at 15psi then other times shoots to 20psi. So from my research that means n75/vac lines/PCV.
Going to service the recirc valve replace the lines.
Was going to just put in a catch can for the pcv.
From what I can see these mods were done car was mapped for them
P0171 code on the basic obd scanner.
Just had it in the garage for the manifold gasket thought that was the issue but no better performance just less tractor like now

If you take the battery and battery box out, it makes access way easier. Get a flashlight and inspect the pipes for leaks of loose hoses.
Yeah all hoses up too seem to be in tact. The hose off the rocker cover is a lil soft so replacing that.
So il have to check under this evening.
Also wondering...the car boosts a lil smoother with n75 unplugged... wondering if that would make any difference to have it unplugged for the emissions test?

Shouldn't have thought so. Pretty sure with it unplugged the lambda sensors are disabled and it's in open loop, but never tried it
New full set of boots. Road trip next week so replaced my ageing tyres that had really bad cracks around the edges.
The guy in front of me ordered two tyres £742 he got quoted.
I’d love to know what they’re going on cause I’m never having one whatever it is.
Apologies actually re read my message. Not got the lean code have the rich code.
Emissions are .59% co2 at 3000rpm. Need to get em down to .3. don't think that it's the cat but having it checked hopefully next week

It’s that time of year again, getting ready for our little trip to the Le Mans 24 hour next week.
Managed to dodge the showers to get my stickers on.
Okay update for anyone with similar jumpy boost issue.Going through it lads... Have the dreaded lean code, boosting all kinds of jumpy, and need to get the emissions down for the NCThave changed the n75 no change, ordered a boost leak test kit, can't get a mechanic for over a month...
Was going to just reorder the pcv system and replace the parts but the cars modded and theres a n249 and pcv delete on it. Can't tell what I should be doing or looking for as all the videos and tutorials are for stock or different to what I have going on
Anyones guidance or encouragement is welcome

Backstory; bought the car heavily modified- boost was jumpy then p1072 rich code popped up.
Checked all n75 piping all the boost pipes ect no obvious errors.
Research was suggesting PCV system, cars had a PCV delete just to atmosphere. Installed a catch can to atmosphere and fresh hoses and crankcase breather.
Car boosting as I think it should well above what it was and no jumping. No more rich code either.
It's still booked in with a tuning shop for next month so il still drop it in for a map check and health check just to be on the safe side considering it's nearly impossible to get a mechanic to look at the car round here.

The radio controlled ‘mini me’ is ready now too. Bit of fettling to get it running straighter.
My lad has challenged me to a race on the famous Mulsanne Straight at Le Mans on the Friday track walk against his Laguna.
I’ll try not let the side down!
