RE: TURBO KABOOOM!
The chip had nothing to do with the turbo. The car does checksums that account for things like that. Keep your chip and let the turbo cool before you shut off the car and it will be fine. And i dont believe there is a 1+ for B5'ers

i love when people try to correct me with wrong info. 
The compressor inlet and exducer is larger on the ko3s along with a more efficient 8 blade compressor. The ko4-15 uses a ko3 compressor housing and wheels, the turbine however is 1-2mm bigger, thats the only differnce between it and a ko3. So yes, the ko3s will make simular gains as a ko4 at a far less cost. As for holding boost longer, it still drops off a 5k like the ko3's

The ko3s has a ko4 compressor but with a smaller shaft and a ko3 turbine. Ko4 holds boost longer and better than a ko3s because of the turbine. just because the ko3s is only rated 5hp less doesnt mean it is just as good. It is not how much horsepower you have it is the area under the curve that determines how fast it is.

just get a ko3s out of the classifieds for under $200. with equal boost they will make the same power. As for priming, just remove the coilpack harness and the injectors harnesses and then start the car 5 times with 20secs inbetween.
ko4 = ko3 compressor (smaller inlet and less efficient wheel) wheel with 1-2mm larger turbine wheel.
ko3s = larger compressor inlet, more efficeint compressor.
The turbos are only rated 5hp differnt.

RE: TURBO KABOOOM!
why would an exhaust leak cause it to boost more at redline? or i guess the better question would be, why does it rob boost at low rpm but not high rpm? i do have a slight exhaust leak tho...

RE: TURBO KABOOOM!
the exhaust leak would be the only way your turbo would boost that late. There is no way in hell that you would have boost at 7k with a k03/4. Making boost until then is a larger reach. The only way this can happen is if you have a leak somewhere before the turbine wheel. Could be a bad gasket or a crack in the manifold or turbine or even a leaky wastegate. Well that, or a severly clipped turbine, but no one is that dumb

RE: TURBO KABOOOM!
lol well now you got me worried. im just gona fix my exhaust leak and hope it fixes the problem. i boost 15-16 psi and then by the time its at 6k its sometimes at 19psi. i never really take it to 7k.

RE: TURBO KABOOOM!
should spike to XXpsi, and then hold set boost to ~5k and then it will taper off. If your only peaking 16psi, i bet your set for 20-22psi min and your car would run so much faster when fixed. Main cause would be manifold to turbo gasket. I would just yank off the manifold and remove the gaskets and then reinstall and see what happens from there.
