The GT4094R isn't great either it ran higher egt's on my truck than the stock turbo and from what I have heard Drive pressure's are off the charts I blew a heagasket at only 40 psi of boost.
I am kicking around my next turbo set up it will either be the HTT, S400 using a wastegate with the turbonetics pedestal or a big VNT
I really want a big twin setup like trent has but I don't have the money
The 40-94r ran verry good on my truck and ran the same egts as my stock turbo but with a tune with more fuell and more power. Tuneing def has alot to do with egts and other things as i have found out.
the cheetha had the highest egts out of all three turbos but still ran verry strong. and was close with the 40-94. the 40-94 just seemed to have a little something more to it.
If this new avnt works like the 40-94r does then i think it would be a really great option. only time will tell thoe. A gt 42 avnt would be awesome if the could manage the DP and egts
