3rd gear, tires are 225/45/15 Rival S, LSD, tons of grip though they could of been spinning as not on the best of roads but the best I have available. It did not feel nor sound like spinning tires. There is a section a bit trickier to use I might try next time.
I would not like to have to use 4th gear, not a good idea in this area, lots of LEO, not many roads, not city like traffic but enough making it hard to find a good place to make runs. My car is the only modified FiST in the area wide tires, lowered, splitter, CF hood, easy to get a bad rep here.
I love living here, wonderful place, as long as you do not have the wrong car for it, why selling it.
What is odd is the 20 PSI at 4k RPM with nice power curve then at 5k spiked right up then back down by 5.5k like fell out of a tree though the boost was the same level all across from 4k to 6.6k.
Usually I end up running in the heat of the day, 80-90 degrees, early AM it was 64 and road temp probably less as sun just up and it was 55 last night, that seems to be the issue.
Even when I had the EFR making around 400HP, on a warm day, good surface, did not spin a bit even in second gear and just a bit off the line in first, lots of torque steer, why I went to a smaller turbo. Unfortunately the guy I sold it two found a better tuner than I had and his power curve was far better, mine was like an on and off switch, not good for real world use except maybe a drag racer which I am not.
I might go make another run the AM when warmer but hopefully hear back from tuner before then.
