Hi guys needing some advice on what this could be I will also post the spec of the car in the post along with as much as I know as I haven’t owned the car more than a week.

ok so bought this car a few nights ago knowing there was a issuewith the gearbox 5th gear is knackered(you need to hold it in place or it crunches) but the guy gave me a spare gearbox and told me the one on it was a lsd box.

anyway so after having the new fuel line fixed from sos motorsport in Falkirk as it spilt as I was coming home from buying the car I noticed something strange while on boost

so what seemsto be happening once I am around 4/5k rpm on full boost it feels like the boost is on one min then off then back on again consistently I am
Not getting a smooth progressive delivery off power and I have even tried this with changing the settings on the apexi avcr to a/b still the same could anyone point me in the right direction to what it could be?
On the attach ment it has the spec list of the car

first, i'd suggest you run a diagnostic and see if any codes show up
also check the map sensor and the hose connections to it and the manifold

The lad who I bought it from said it could be the spark plugs he gapped them he said it could maybe be down to that.

so I am going to buy new spark plugs today fire them in which ones should I get for this set up?

Sorry to hear of the drama mate.

As already mentioned, check for fault codes as it might narrow things down.

A cursory check of all the boost and vacuum lines would be recommended too, along with inspection of the plugs.

Also what sort of boost is it running?
