Oh man. That's a tough question. It pulls hard, but i haven't had a good enough stretch of road to wind it out 2-3 gears or so. I will say that the biggest change I noticed right away was that it doesn't run out of steam at 4500-5000RPM like it did with the stock E7's. Now i have to pay attention to my shift points rather than being able to feel when it was running out of breath.
I need more time to really evaluate a SOTP feel. Was it worth it? I'd say so. A lot of what i did pertained to refreshing the car in general vs just trying to improve HP numbers. I wasn't going for big numbers as a goal anyway.
Once i get this thing tuned up, i will head to a dyno. It's an hour away unfortunately.
I am starting to think I want to step the 3.73's down to 3.55;s or 3.31's. Need a little more time to think about this. 1st gear is too short and too aggressive just trying to get through an intersection with regular traffic.
The
Borla's do emphasize the cam chop more at idle now than the flowmasters did. Even though it's a tad bit quieter, it's more distinct and pronounced. That alone makes driving it fun when you come to a stop sign and hear that cam chop. It's actually pretty darn driveable even untuned.
Also...i'm still on my 19# injectors, so trying not to go too hard yet. I really need to get my Megasqurt in, add the 30#ers and tune this MF. I need to build the adapter harness, but i want to drive the car a bit first.
