Help!

I have an RB25DET which has been tuned on an aftermarket computer and has always run fine. The other day after altering the boost to a higher psi (maybe to high) I went for a drive out of town to see a mate. As I left his house, I put my foot down and gave it a thrash out of his road.. Upon doing so, the car assumably over boosted almost 2 the point of detonation. I instantly pulled over and adjusted the boost back down to 10psi and carried on my way. The rest of the way home the car drove fine until I got 200 metres from my house and it started loosing power, chugging and dieing slowly losing power as I drove, until it eventually stalled as I rolled into my driveway. It has been parked up now for a week as I have been working and havnt had time to sort it. I went into the garage to day to have a look at it and everything seems fine (visual wise). It takes a wee bit longer to turn over now but idles fine when started. As soon as I touch the accelerator to give it a rev, it just starts chugging and wants to die again.. Also stinks of fuel like its over fueling, and has a rather big pool of condensation out the back of the exhaust pipe!

Any thoughts or ideas would be great, PLEASE HELP!

Popped an intercooler hose off is a likely guess.
