Hi, out there..
I`m living in Norway and I have some fuel adjustment problems with my MPI SC. It feels like I`m not able to lean out the sled enough with the MPI controller box at low RPM. It feels like the sled are cutting ignition when I left my thumb of the throttle when I`m driving at high altitude. I have heard that the Boondocker box will be easy to adjust compare to the MPI controller. What kind of box do you guys think I should go for? Can someone tell me if I can use the same box that the turboguys are using? If so, where can I buy the best box to my supercharged Apex?
Does anyone now something about this? I will be happy if someone can give me some answer

I have used Boondocker controller with great success but my understanding is if you send your mpi back to them they have upgraded mapping that is working well

I Have occasionally some problems with TORS, but my main problems just show up on high altitude. At sea level the sled is running just fine. I run the sled with 3 head gasket and 26/22 tooth on the charger and motor (11.8 psi) And without BOV.. The kit is brand new (feb 08) so I dont think I have to upgrade the MPI controller.. Do the Boondocker box come with display for easyer adjustment?

Yes the boondocker has different displays for different rpms and boost,also has a memory for high boost etc. cansave several different maps too.

We are using version 13 / mpi on 2 apex supercharged sleds .
Each have over 4000km with sc and run excellent , running just about the same amount of fuel running against stockers unless you push hard then milage goes away !

Ok then, but the sled isnt running well over 6-700 feet and the milage is bad.. I have tried to lean it down without success.. It still cutting ignition in high altitude when I left my thumb quickly of the throttle. I want display for the adjustment so I can see what actually happen.gsxr said:
