The ihi turbo is only a 62mm where the garret vgt is a 64mm. You can pick the garrets up for cheap. I find them for sale all the time for $400-$800 rebuilt or used. so depending on what the controller costs, it may be a budget turbo upgrade.
One member above mentioned going with aftermarket also. That is more what I was refering to, there are to many people who try and claim a VVT turbo is not a good upgrade. Where they are and there are solid numbers backing them up.
but aso, it would not be automatic like turbo braking on the newer trucks...tere is now way to program it to come on under 0% throttle....well unless your crazy like ben or brayden
