From S16g to E316g on same tune....car bogs in lower gears now

[4gfun]

I have gone from a s16g to an e316g. I haven't done so much as even touch the boost controller yet.

I took it for a spin and the new turbo builds boost just fine but:

1) It sounds completely different.

2) The car bucks and wants to die if I give it WOT in the lower gears. In 3rd gear and up, I don't experience this.

I wasn't aware that I'd have to adjust my MBC or my tune for such a small change.

I'll post some logs soon, but was wondering if that seems right. It seems like it is running richer after the turbo swap (as rich as 10.1:1). I'd figure that it would run more lean automatically after a swap.

Also, my Dodge Modded BOV seems to be making all of the noise now whereas before my External Wastegate would just drown all other noises out.

Thoughts?

Thanks

Has a Boost leak test done?

Suddenly rich with literally no other changes or leaks = Moving less air

Pull some fuel in the problem areas and try again.
