I have been introduced to both for my 06 F250 and I can't figure out which would be better. I have heard good things about both but what I really want to find out is the negative things. Anyone got any details? Thanks

If youre sticking with 180 injectors, id most likely stick with a VGT-SS. I ran a Silver Bullett 66 on a 6.0 and it was laggy. around 2100-2200 it would start to light. with a high stall converter youd light it, but the vgt-ss would do a decent job of cleaning things up and have great spool. Youd have to ask logan what kind of temps hes seen with 180s-190s and a VGT-SS. Id imagine a 62 such as a phat shaft 62 would be a better match to those injectors than a 66, as you could still push in the 500 horse range and temps would probably be somewhat managable and spool wouldnt be terrible.

LOL apparently we were posting at the same time.

With Elites stage IIs and a reg. return, on insanity tunes, the vgt-ss would peg a 1600* gauge fairly easy at WOT. But driving at 70mph, egts were around 650-700 with stock IC.

With the Phat Shaft 62 the Egts never exceeded 1500* at WOT, and were in the same range at 70MPH.

Phat shaft 62= Hair of lag on the bottom end.
Vgt-ss = Quick spool

both would produce rite at 40 psi.

i know DJ sells a package deal for around 4500..fuel system, 190cc, VGT-SS upgrade, and studs. which is a bargin and seems right up your alley. DJ claims to see in excess of 500 with this set up.

Innovative can do something similiar.

Elite tends to be a little pricey, tadd does do good work but you can get comparable power else where and save 1k..imo

Personally I would Run the Phat Shaft 62, I cleaned up almost all the smoke on the top end, and power wise I think the phat shaft felt like it had more power on the bottom end once it spooled.

The VGT-SS was just more of a consistant power from start to finish. It also was vary close to no smoke aswell.

Both operate well, and Its depending what u are going to do with the truck, daily driver in houston, VGT-SS. Open road towing PS62.

I have run the VGT-SS on my race truck with a lot of success. I have no complaints.

SANGER already has a 66mm from us, but I suspect there are some other issues preventing it from performing as it should. I believe TN has even tightened the A/R in an attempt to help spool up, but I am not sure what has happened since.

We have had a few trucks with the same turbo, but with an injector variable, the performance was not the same. We just went through this exercise with IGOTIT's truck.....

A variable vane drop in with a GT40-88 comp-wheel would be ideal. With fuel tuning already adjustable, somebody will have to write software that can program the turbo to operate optimally. I talked to Borg Warner engineers about the stock turbo and to see if they were working on an upgrade. They had 3 Powerstrokes using some s-200s variables that were running around. They told me that I wouldn't believe how many things the EMCM looks up to control the vane position. Just about everything. I have some S300G variable position turbos brand new that fit DT466's but have no way to control the solenoid. I know what the pin out connectors are and that's it. I could regulate voltage to them with the use of a pressure switch and thermal switch but this is still a blind way to tune the thing. I think we need to develop VGT Turbo software that can be used to tune with injectors and other modifications. ANy body know how to write C code?
