That makes sense, but its hard to believe that the guys running FBO with JB4 on map 2 or 5 that are posting 350-370 whp from the dyne can be THAT far off from your 297 or whatever it was. Im fairly new at this so I'm just trying to understand. I appreciate the knowledge you're throwing at me

To me the dyno look like the car started to fall on its face at 5700rpms .?? It's just from what I see from dyno sheet ..it peaked higher the. Stock turbo tho .. I'm sure on 93 with e85 mix it will put some good number ...

But on 93 and 14.5 psi, gains are already impressive. |

How will you know if the turbo made a difference from your first turbo build if you never dyno the first turbo on you car to begin with? Would be great if you could slap on the first turbo and do a few dyno pulls with that.. regarding stock turbo n55 on map 2 ive seen many dyno in the range of 310-340 depending on dyno..

That's a great % improvement for the money. Mustang dynos tend to read significantly lower than Dynojets, 297whp for FBO on 91 and Map 2 makes sense.

Yes, Mustang dynos are usually at least 15% lower than a Dynojet sometimes up to 20%. Like posted the big difference is the delta. I can't wait to see what it does by someone running e40 or meth compared to their FBO. If it is still a 45whp gain that is a great deal! Should get us solidly in the 11's.
