2.3 Vmp phase 3 upgrade

[B7213]

I have a 2015 gt premium with the roush phase 2 supercharger kit , ngauge with a vmp tune. Has anyone ran the vmp phase 3 upgrade. Was wondering weather the bigger injectors , 1 mm smaller pulley and and jlt cai will make that much more HP. I know I'll make a little more was just wondering if anyone has and what kinda HP deffernce they got. Thanks

It’s all going to be in the timing/tuning. 1mm pulley diameter MIGHT be 8hp. The whole phase 1,2,3 terminology is a joke.

a CAI, 96-98 octane fuel and 2° more timing should be good for around 20-25whp more.

Yea kinda what I figured, gotta get some traction before I worry about more HP. Cant do anything with what I have right now with advancetrac off, cars useless until about 60mph even then it spins. Going to put nt555r s back on this weekend,

555R’s don’t get enough credit. They are just as good as any other R compound drag radial when warmed up and at the proper PSI.

Yea it gets hairy when your car get sideways at 60 + . I always got good traction with the nt555r .I put some more cont. Extremely sports on it case I was driving 500 plus miles a week. But they don't hold the road on that much boost. So since I don't have to drive it every day I'm going back to nt 555r they hook when there warmest up
