Smoke while shifting on boost
Just finished doing a top end rebuild, and the 930 has a tad over 200mi on it. Got it dialed in pretty good and it runs perfect, except when shifting on boost where we see a puff smoke. No smoke at any other time. Heads and jugs redone ect with new rings. Just changed oil at 150mi and put 10 qts in so I dont think it would be too full. Did not mess with CIS other than replace some questionable hoses. Running a stock WG spring as far as I know. Opens at .8 bar and full open at 1 bar with a tool I rigged to test. Stumped about this puff of smoke... any ideas? It has aftermarket air box, IC and exhaust. 50k miles. Thanks in advance. -Jamison.
