Here's an interesting question. I think everything looks good, but now I wonder about my HFCs. I've had the F.I. HFCs installed brand new at the same time the turbos were installed. I'm pretty much past 30k miles with the kit and the HFCs.
Think the HFCs clogged might be the reason for the slow spool or slow revving? Also, maybe it's the reason for the engine dying at idle on startup at times?
