So the turbo went on my 05 lgt. i think it was from an oiling issue since i would periodically get a P0011 code when my oil would get low due to a leak. So looking at getting a new turbo (also going to fix the leak and take it to a shop to diagnose the code and make sure the oil lines to the turbo are fine).
but question for the turbo.
What should i get? Vf40 cartridge ($240 + install), vf40 new turbo ($300), vf46($350). I dont think I want the 52 at this point.
main question is: I know the vf46 is a direct bolt on. but will i require a custom protune on the car? I am currently running a 06 ECU with the cobb stage 2 tune on it. I want to get the car protuned at some point but its a couple hour drive to the shop to do it. Can i install the 46 and run it on the same tune or will that cause problems? What are the main differences between the 40 and the 46 if they are brand new turbos?
if i go with the 46, do i need to modify anything on the turbo or switch anything over from the old turbo?
