C30 D5 Tinkering

[David P]

From the bodged job with 2.5" pipe sleeved over 2.25".



To a proper job with 2.5" all the way.



Also had a dyno run, but it transpires that the job is not jobbed yet?



With the exhaust and intercooler upgrades, it should have more power than this.

I have contacted BSR and asked what may be the cause. Response below.

"Most common problem when having low power on this model is

- defective fuel injectors (most likely).
- leaking EGR
- defective boost regulating system."

Given multiple options, I'll begin with the cheapest and easiest.

I haven't yet fitted a new fuel filter, so will try that first and give the boost regulator a good clean, because that job is free.
