Default warranty issues w/ blown head gasket and minor mods?

Went to Rennick today to buy rubber floor mats, since we've had rainy weather in Socal. On the way home 5 fwy northbound was a friggen parking lot so got off some where in La Mirada. While driving the STI spiritedly on the side streets, I came to a stop. As I took off I mashed the gas pedal, then next I heard a burst from boosted pressure that definitely didn't sound right. Next thing you know car would stall at idle. It would start but it would die a second later. With just by the feel of the motor stalling, I knew there was a definite loss of compression.
Well, I've only had the car for a couple months now with only 10885 k on the motor, it's still under factory warranty. I had it towed back to Rennick where they will diagnose it tomorrow. The only mods I have are a Turbo XS fmic with HKS ssbov, Invidia catless dp, and Blitz Nur spec Touring cat back exhaust. Should I have any warranty issues?
I heard they are mod friendly dealer but I've recently read some posts of thier service department getting strict. I don't see why, they have an extensive line of aftermarket performance parts. If worse comes to worse I can tow it back home and reinstall everything back to factory, tmic, factory dp and exhaust. Anyone have any experience with them in this situation?

1) its not your head gasket
2) one of your FMIC hoses blew off, or is leaking just enough that there is air leaking out and causing you to run rich enough that the car dies at idle.
3) you should not be covered under warranty with the mods you specified. you should not even expect to be covered under warranty with anything more than a TBE installed.
4) assuming specific parts broke (head gasket) and it being a warranty "issue" is a little ridiculous. do a search next time, and then post questions if you really cant find anything.

Default update

I was at Renick today and while I was there to find out the status of my STI, William at E Auto called my cell as soon as he read my thread. William knew I was only running the stock turbo with no boost controller. He told me to check the silicone hoses on my fmic piping and see if the one on the driver's side under paneling got disconnected. I had thought about it when it happened but it couldn't be because when that happened on my boosted integra the car still ran.
So I checked it out and he was right. It was that particular hose. Since the STI uses MAF sensor if any of the hoses disconnect it will give the sensor a rich reading and make the car die at idle. I didn't realize since the teg is speed density it would still run. So my nightmare is over.
Thanks to William at E Auto for his concern for my situation. E Auto's got some great guys over there.Thanks to Christine @ Rennick, she had one of the techs reconnect the hose at no charge. But as far as a dealer they were going to do everything they can to help me out. Both of these companies got me as a customer for good.
Thanks happasaiyan you were also right but didn't read your post until I found out the hose blew off. Thanks anyways.
