-aFe Power Cold Air Intake Stage 2 Si Pro 5R
-Evolution Racewerks Chargepipe
-Sprint Booster v3
-JB4 Map 7
-E85 w/ Walbro 450
-Mhd Stage 2 plus +

Yeah, that doesn't make sense.

One or the other, probably 340-350whp at most.

You either run a BEF + JB4 OR MHD flash only. Not a MHD flash only tune AND JB4. They don't work well together.

Just remove the JB4 at this point.

Once you upload MHD, you have to upload a special BEF to it that works with JB4. I think if you don't JB4 is pretty much worthless.

Saying that you're running E85 on just a LPFP isn't true. What is the E content you're running?

Yes you can use the jb4 but you're using the incorrect mhd map to go with it. I don't know where you were told you could use an off the shelf map but that is not correct. The standalone MHD maps and the MHD maps for the JB4 are different.

Isn't their a flash only mode for JB4 now? It's like 4/2 is bef and 4/3 is flash only. Nonetheless I agree that you should either take out the JB4 or use a bef map.

According to Terry, yes. According to Marshall (however he spells his name), no.

You need to change the Jb4 steering wheel settings to 4/4, as it's been stated many times that MHD OTS maps and JB4 don't work well together and could potentially damage something.
