Hey guys. Loved reading through here and getting some good feedback that matches what we have found. Here is the deal. Bikeman tunes run great. But that dip in the dyno is legit and does happen. The point is, you can clutch around it. That's why most people with good clutching don't notice it. Ibexx knows what the problem is and has fixed it. It sounds like the guys at maptuner may have figured it out as well. I've never used theirs. The ibexx tune has more control over the factory wastegate than the bikeman. They close it earlier and bring boost in much faster. This gives you much more bottom end and makes it a lot more fun to run on the higher power levels. They also have a killer clutching package that is designed specifically for turbos. With their proprietary profile on both the weights and the helix they are able to hold stage 4 power on right around 80 grams. This helps the off boost power tremendously and makes the bottom end even more snappy without sacrificing control. It's hard to explain here but if anyone is riding island park next week I can meet up and let you ride one of our sleds.
I also want to address the fear of blowing a charge box up. So far we have never seen it. The charge tunes will split but we have been testing a big turbo replacement and running around 15 psi of boost and still no box failure.
Thanks guys and hope that was somewhat enlightening on how it all works. Heck us out at
