I haven't done it with mine but could haveif I wanted to get aggressive with my tune or even run it up to 6250 for that matter. My tuners didn't foul the plugs out while tuning it either.

P.S.: I was happy reading the thread with no intention of replying untilyou couldn't resist throwing that out there. I don't know what you have done underneath the car to make use of the new-found HP but I will back mine up the old fashion way and run ya instead of throwing out price lists and sarcastic remarks.

What kind of turbo was this? Did I miss it? With A/R ratios make, etc.
