Hi all,
I have a 1.9td on a Lucas pump and done stage 1 tune pushing 18-19psi on a T2. It's on only 80k and full history. It's a great little runner. I'm sure it's mechanically sound. However I recently put a de-cat pipe on it and loved the way it spooled up quicker so bought a full 2.5in custom made exhaust with no middle box (used) as I'm also waiting for a 9mm Bosch pump to be delivered and will be putting a TD04 on also.
Problem is I fitted the exhaust today and its blowing shit loads of grey not black smoke out when on boost. What's happened? I was pleased with the tune as no smoke but a bit of haze when nailing it. Will it settle down after running it a while? Or is there a problem? Any ideas guys?
Cheers. PC.
