I've been running map 3 on 93 octane for awhile now. I ran a data log in map 2 and 3. Sent it to burger and they said looked good.
I'm very impressed with this jb4 also.
6mt with zero mods other than the jb4
415 hp and 420 tq bone stock at the wheels it very very impressive. You must have a fast one there.
i have the jb4 on my 6spd. Car lights up side ways in 2nd and i have to be careful in 3 hitting it depending on pavement.
stock car.
I've also ran map 3 and had the data log confirmed as gtg by burger...
however I'm not running the fuel wires or the ewg so I just run it on map 2
