Default Driving a turbo car untuned

I'm in the middle of a twin turbo build and having trouble getting my exhaust aligned on jack stands. I have access to a shop with a lift about 10 miles from home but the car is still on the N/A tune and my tuning appointment isn't for 3 more weeks. I'm assuming that if I unbolt the blow off valve the car will have no chance of building boost and I should be able to limp it. I'm still running the factory injectors, just wanting some opinions on my best course of action.

If you still have the stock injectors and map sensor you will be fine driving it as long as you dont get into boost. Just limp it there and you should be fine.

My 2 Bar MAP sensor is currently installed, should I install the factory sensor again or can I leave it as long as I don't get into boost?

If you remove the blow-off valve, it won't run since it will be sucking in un-metered air (air downstream of the MAF sensor)

Like 'GaragedLS2' said .... just stay completely out of the boost.

Install factory injectors and MAP sensor and it should be OK to drive to tuner.

Stay out of boost, obviously.

Put your old map back on and you'll be fine, just unhook the intake tube from the intercooler. Then its no difference than it was before, thats what I did with mine.

The blow off valve is pre maf so all the air entering would be measured.

I'm pretty confident given the responses here the kit is 90% complete I just can't get the exhaust to line up properly on jack stands even after shortening it about 2".
