MintLord Posted October 16, 2017 Share Posted October 16, 2017 Hi all, Thought I'd just get some ideas thrown at me to diagnose what my issue is. I seem to get some spiking with boost on the primary turbo, and low boost on the secondary. Primary Turbo will spike to 17PSI quickly, and then will settle back down to 13 very quickly after hitting the 17PSI number. The second turbo seems to sit at 13PSI constant, no higher or lower. Definitely is more power on the second turbo, but 13 seems low from what I'm reading. I'm definitely not ruling out bad Boost gauge, but I don't think that's the issue here. I've got the boost gauge plumbed into line 11, just out from the BBOD. Any Ideas? Obviously most likely Vacuum tube issues - I had a leak from my BOV, after installing an aftermarket BOV, and adding some gasket maker to the BOV, it's been much more consistent. So potentially more boost leaks elsewhere? All testing I do of boost pressure is around 90-100km, and usually third gear pulls for the second turbo.
