FI choice validation

Utilizing a GT3076r but still making more power as soon as the pedal is depressed, and this is compared to other top kits out there with smaller turbos. It is nice to have an out of the box kit capable of 500whp

I like Ptunings kit, only negatives I see are no diagonal "chassis" bracing due to design and using stock header. I'd be that guy getting the cat breaking down and Effin up the turbo. I understand they have a header of their own in development but meanwhile there is some risk in existing design?

Risk? Technically yes, but the rate at which the cat will decay and throw things into the turbo is highly unlikely in a new car like this. Albeit I'm waiting on their racing header to pull the trigger on the kit so I can feel safe about it, but @ptuning told me in some PMs that it shouldn't be an issue for a long time.

So the PTuning kit deletes the diagonal chassis bracing? Is there some aftermarket diagonal chassis bracing to add after the fact or would it just be in the way?

It has already been established that turtles are just as sweet as a turbocharger.

Stay safe, adopt a turtle and name him turbo.

^^ this. If I ever go FI that's what I'll try to do, even if it means flying out to california to 'borrow' the CSG car lol

i would have to disagree with this. i don't often find myself making full-throttle runs from 2.5k rpm in my actual daily usage of the car. i find transient response above 3-3.5k to be a far more important metric of how a given turbo setup performs, in terms of it's impact on real-life driving.

i guess it depends what you're going for in the end, but to me i'd want to base my decision on data gained by replicating how i actually intend to use the car, or will likely use it.

I didn't necessarily mean stomping on the gas at low RPM. It can be done at high RPM, because the test is for transient response.

I'm more into some slow lorris...name him speedy or something
