So I was on my way home from an autocross this past Sunday, I floor it, and immediately feel my clutch slip like crazy (despite the fact that I was on a neutered tune). I let off the gas and noted this (on a tune that commands ~2.20 load, ~19 psi):
I immediately knew what the problem was. I drove the car the rest of the way to my destination, and I found this:
That's the wastegate to EBCS line. (I bent the line like that to show the cracks)
If I had been running my E85 map, there's a good chance I would have bent a rod (although on that map, I run really conservative load and boost-based fuel cut values, so I think it might have survived). Luckily I was running a 93 map with ridiculously neutered timing.
On the following day (yesterday), I drove into work and suddenly my car leans out, starts bucking, and my fuel trims max out positive. In total using a boost leak tester I found two more failures in my siliconeintakes.com tubing that I used to plumb the EBCS. I use both 6 mm and 4mm tubing, and in total there were two failures for the 4 mm tubing and one failure for the 6 mm tubing. I'm guessing at the autocross, the under hood temps got high and killed the tubing. Now that I fixed the leaks of course the car runs great again and the intake system is tight as a drum.
I'm creating this thread for two reasons: To deliver a warning about this tubing, and to hopefully get some input from you all on where I can buy better tubing.
