Then, I had a eurocharged ecu flash (removed race chip). Car was slower....only did 11.0, at same track, and same fuel, and same weather. Low and mid ranges were improved over race chip, but top end was dead. Throttle closures, etc.
Removed ec flash and went with weistec ecu file. Strong low, mid, and top end. Car did 10.6 at 130 at same track as before. Great drivability too.
Now have stacked jb4 on top of weistec ecu flash. car does 10.2 at 136. We'll do some more tuning on the ecu file in Feb when tuner in town. Car has superb streetability, and is fast. Very happy with this setup. JB4 is a cool tool.
Car also has awe intakes, remus catback, and beta tcu tune (will be revised).

Getting both seems to be the best way to go! I started with JB4 and now that I have meth injection I'm going with likely a DME flash to take full advantage of it, but keeping the JB4 to get a little extra boost at the track and to be able to drop into the valet map if the meth stops flowing. Its definitely a good tool to have even if you have a flash. |
Makes sense bud. I've had good success with DME...should be a rocket once done.
