Having had my car for 10 months I've finally got my first problem.

The cars been mapped for 1.1ish boost but completely randomly I'm now only getting 0.7 ? The car felt a bit slower and it was clear why when checking out the gauges?

Any idea as to why this would happen all of a sudden ?

Cheers in advance guys!

 

Could be a number of things tbh.

I had a car run very lean once and that effected the boost and ran alot hotter as you would imagine.

Turbo maybe on it's way out.

Boost pipe is leaking may have a small split or hanging off. Also check gauge pipes.

How does the engine sound any knocks bangs or rattles ?? or any smoke

 

Nope all good checked the pipes I can see and no leaks that are noticeable. Will clamp of the gauges later to see if that improves anything.
