Please log your boost curve upon completion of dyno. I mean, that is after all the number 1 reason to make it twins vs. single right?

I have tons and tons of info on all the work I do...but I will for sure....as far as traction goes I was putting down 500 whp and didn't have a problem with traction out side of first and tires warm..and that's on stock 2014 rays

Surprised to hear this. My car has trouble putting down the power even in 2nd. Running 305 PSS's and whiteline diff bushings.

Mine will get sloppy as hell in 2nd, and I'm probably only putting down ~480whp or so.

I always wonder whats really going on with traction. I have around 500 and I spin through 1st but hook up pretty hard in 2nd, in summer.

And 10 lbs on E85 with 16* timing is plenty to put me in the range of "I should be losing traction".

hmmm. i also have 500+ and i have traction in all but 1st and part of second.
now i do have a wheel hop problem i am chasing but once she is rolling shes gone.
i dont think 500 even 550 is to much power for the street, out of boost the car drives just like stock
