I have a 1057 converter with a 6" lift 35's and stock gearing I am getting a GT4094R turbo. This just occurred to me. Will I have lag problems with this setup?
Will it spool

what paint said the 94 shouldnt show you any problem at all and even if its a little slow to spool tuning should fix it... gt42 you might have problems
tho other will tell you differently
i would get a .95 ar hoursing vs the 1.06 the comes standard option on them..cruising at
55mph is ~1400rpms
65mph is ~1600rpms... boost guage is 0-2psi on flat ground
IMO the stock trubo is pretty laggy in those areas... i am sure the bigger turbo would amplifiy that..
when i towed my 75 form cali to OH anything under 70mph the truck had a hard time and lugged pretty bad when you hit any med size grade/hill.
personaly i re-adjust shift point in T/H via efi live to were 4-5 is ~65mph ~2300rpm helped fix that problem..
i know drew/paul dieselon ran a 4088 wiht 6" and 35" ran an .85 or .95? to keep egt in check while towing
I think you will be fine
Use the O/D lockout on hills if you need to or change the shift points

I helped develop this converter on Casper in '05. Pat can tell you what turbo he was running but I think you are going to be fine. you may even like the converter better.

I had a HTT with a 1057 on a 7" lift with 35s......I think i can give a fair opinion
It spooled very well for me and im pretty high in elevation.What are you basing your info from, Adam
What are you basing your info from, Adam
principle and experince with other trucks.
We ran the 1057 until we went to the GT42 May of 2007 and you put a ML Precision. Then later I believe you put in a 1055 ? same # that is currently in Casper.
Its nice with 35s also for that since you can run pretty hard in 4th keeps EGTS down and pull like a mofo
The converter is only an issue in first gear launching as far as spooling goes. I towed a steel car trailer with car up some steep mountains with a GT40 with the 1.06 hsg with zero problems. If anything, the 1.06 GT40 spools harder than the stock turbo.tho other will tell you differently

Please...
I've spooled a GT42 with a 1057, it's just a matter of tuning. The converter is only an issue in first gear launching as far as spooling goes. I towed a steel car trailer with car up some steep mountains with a GT40 with the 1.06 hsg with zero problems. If anything, the 1.06 GT40 spools harder than the stock turbo.
The HTT I purchased from you Pat would spool very very fast
It was alot to do with tuning,But it was faster than the stock VVT
i tend to agree... with one excception...
casper had "shorter legs" by ~10% then my truck, kevinL and simons when you are runnign the GT. iirc you were still runnign 3.73 vs 3.54 adn a ~30" tire vs 3.73 and 35" or taller
racing and DD... probly will not notice it..towing he will.
I respectfully dissagree
Its alot to do with the tuning and DSP works great for that
