Need help. I am upgrading my 380cc injectors to 600cc DW injectors and Walbro fuel pump. My question is after I make the swap can I drive it gently to a tuner without changing maps? I dont have a cable.

You will struggle, I tried to drive mine around for a few days with 600cc DW walbro and a fuel return (with a vortech v3 also). It ran pig rich and bogged down a lot even with me reducing the fuel pressure. Ended up having to hire a trailer as I didn't want to damage the engine.

I wanted to do the injectors myself but now i think ill have the tuner do them. Thanks for saving me a hassel!

No problem, I had a 240 mile trip to my tuner, it would have been fine if the road was flat but any hills/load on the engine and it really struggled, so much so I thought the car was going to come to a stop once

That's what I would do ... bring a 10 12 and 14 mm a 3/8 ratchet ans if you really wanna move fast an electric impact.tuner may not like it but in that case do it a few blocks down

I just had the plenum and intake off and on with new gaskets, do you think i will need new gasket kit?

In vacuum you have 20% o2 correction so if you are light in the throttle then it should be fine.

Do you have a return fuel system with an adjustable fuel pressure regulator? You can drop the fuel pressure which would make those 600's act like smaller injectors for the drive.

No, single line feed. But good thought
