1.0 exhaust housing, big difference?

[Tubbyman30]

Hi, I'm looking at a turbo with the 1.10 compressor housing, EBV delete and a 1.0 exhaust.

Is it much better than my stock turbo with just the ATS Comp housing? Truck is a dd and tow truck in summer.

Thanks for any info.

I believe my stock exhaust housing is .84?
