VGT and NON-VGT Turbo's what's the difference

Ok I'm gonna go ahead and say sorry for this up front cause I know somebody will look at this and say I should have search it but I have which is why I'm posting this. As you can see in my sig I'm running Warren's 190/75 injectors and I want to clean them up so to speak. I'm rolling coal and it is pissing me off I want some direction please if I should stay in the vgt family or would suit me better to go to a non-vgt turbo. If somebody would be so kind as to help me understand the difference, can a non-vgt flow more air or what? I know Adrian(madpowerstroke) is building a stage 3 turbo and it seems like it will clean up 175's but he still has alot more testing to do on it and I don't know when a stage 3 will be on the open market and I'm tired of the smoke. Please help

You could have your tuner "detune" your injectors not to roll coal until you get the right turbo

Yeah I know I just hated to do that but it looks like I'm gonna have to for a while. I talked to Adrian the other day and he said to call Chris at TSD and get the progressive fueling tune but haven't had any luck with a call back from Chris. I will try him again tomorrow but just was really wondering the difference and what would better suit me?

From what I've read, NON-VGT flows more air but you get turbo lag. Where as VGT doesn't have near as much lag but will run out of air up top.

Ok that helps a little bit, I guess it's like picking the lesser of two evils?

Yea it's pretty much what you plan on doing with the truck. A lot of people don't like towing heavy with a non-VGT because when it's in overdrive and you roll down on the throttle it won't spool like a VGT will. However if your drag racing then getting a non-VGT spooled up for a launch isn't really a problem and you have more air in the upper rpm range.

It depends on what you use your vehicle for and what you want it to do. A VGT turbo has an electrical solenoid that actuate a set of vanes for optimizing exhaust flow to the turbine wheel for spool up where a Non-VGT turbo just has a turbine wheel that must be spooled with however fast and hot the exhaust gases enter the housing. Smaller A/R housings spool quicker than larger ones as it creates more pressure to get the turbine wheel spinning. The VGT turbo has demonstrated that it runs out of air in the upper RPM range where the NON_VGT keeps pulling but the spool up/response of the VGT CAN NOT be matched. I would say if you need to tow, get a VGT if not and only care about street/track use, get a non-VGT but believe me (as I was wanting a non-VGT until about 2 months ago) I would wait to see what MAD develops. I have TSD's progressive fueling with my 190/100s and as long as I stay less than 30% throttle, I dont see any smoke. Hope this helps a little.

Windrunner408 that helps and maybe will even calm me down a little bit. I do plan on towing with it and would def. love to have one of Adrian's turbo's just wasn't sure how long I would have to wait but if the progressive fueling will take away some of the smoke then I will go that route for now. Thanks for all the info from everybody

Yea man I have to say to at least give the SPD a shot. It is totally worth the $75 it costs. What tune(s) are you running now and is/are it/they tailored for your 190s?? What are you seeing for cruising EGTs?? I see 750F at 70-75 mph.

What is progressive fueling? Sounds like any other tune?
