I need some advice for a new turbo. I’ve been looking at the ATS aurora or fleece cheetah. I wanna keep my exhaust brake.
Anyone how they either of them work with bigger injectors? I don’t pull to often when do it’s only a 9k camper. Mainly a daily driver.

What did you end up going with? I put an Aurora 4000 VFR in with stock injectors and existing raceme tuner in and couldn't be happier. I am not really an experienced turbo person. I wanted more power than the stock replacement that the 3000 provides.

 

Both the ATS Aurora and the Fleece Cheetah are solid turbo options, especially if you want to keep your exhaust brake. Here's a quick breakdown:

ATS Aurora: Known for its durability and smooth power delivery. Works well with bigger injectors like your 45% over S&S injectors. You should still be able to keep the exhaust brake.

Fleece Cheetah: Also popular, especially for daily drivers. It’s good for bigger injectors and supports quick spooling, which helps with drivability. Exhaust brake should work fine with this too.

Since you’re mainly using it as a daily driver and only towing occasionally, either turbo should meet your needs. It’s probably worth checking with Coffman Customs to see if they have a preference for tuning with one of these turbos.
