Calling JB4 users in Calgary .. I've just installed mine, and well, it's not really as great as I thought it would be.
It's certainly a little quicker, but doesn't feel night and day like many people say.
Does our altitude effect the performance gains of the JB4? I didn't think we were high enough up for that. It feels especially anemic under 3,000 rpm, and has noticeable turbo lag.
Initially I tried map 1, on Husky 94 .. I then did some logging on map 5, which apparently looks good according to BMS.. and now on advice, I'm running on Map 6 with added boost down low.
I put some V-power 91 in this morning, and it feels almost as slow as stock. I had to check that I wasn't on map 0!
I read people post things like 'wow', 'omg', 'JB4 super fast', 'wheels spinning in 3rd' etc .. but I honestly don't feel like I can say any of that.
My car is tune-only + BMS drop-in.
Am I expecting too much? Do you think I should get it dyno'd? Where to go in Calgary for that? LOL questions galore!
