I recently tuned my X and during the dyno sessions we found that there is a huge dropoff in power after 5500rpm, which is consistent with a boost leak. We saw the dip prior to the tune as well...so we ruled out the tune itself. We're going to do a boost leak test on it within the next 2 days.

So, for those of you who have tuned or have dyno runs under your belt...have any of you had an issue with boost leaks? Just curious to see if there are similar cases of shoddy hose installs from the factory like the 8s and 9s.

 

I'm getting my tune soon by GST, I'll let you know my results.

 

No, no issues whatsoever.
