Ok i installed my Greddy Profec B tonight. Took it out for first run. Wasn't working right but got it fixed and was running great at almost 1 bar boost. Came back to the shop and checked my fuel gage that i have mounted on rail. I had the fuel pressure set for 45psi in the program and it was at 30psi so i turned it up to 45psi. Took it back it and fine again then a friend drove it and then the problem started. In any gear when he got to 5500 it would cut out as if he just shifted the car. I'm so confused so if any body could help me i would greatly appreciate it. If anybody needs to know i am using a Hondata stage4b.

 

Hmm. did he happen to mess with your rev limiter? that red button begs to be messed with.....were you in the car when he drove it?

 

yes i was with him. when we got back i reset the hondata with the red button and it still continued to do it.
