Have an 06 QC auto and have decided to go with the XZT and probably the boost fooler as well.

My question is what will the stock turbo handle for PSI and do I need to worry about draining the rail while towing 8500-10000 lbs in the hills?

I have gauges so I can monitor the boost and pyro levels but will the fooler and the xzt combo push the turbo too far under heavy loads?

Anything else I should take into consideration or look out for with this set-up? I do not have fuel pressure gauges but I can easily install them if recommended. Thanks for the info. -Jeremy

 

You do not need to buy the boost fooler if you buy the XZT. The XZT already has this built in!

 

I should have read that other thread first, I now realize this. What about the fuel rail drain?-Jeremy

 

The XZT is not even close to draining the fuel rail.

The only thing I have ever seen give us fits are very weak stock lift pumps. I would say that is the exception rather than the rule though.

 

Thanks Quad, no one better in the biz than you.-Jeremy
