@nicholasliz0420 I'm almost at my goal I just keep hitting little snags along the way. Once I redo my intercooler pipe to 3" for the blow through maf It should hit 400whp after I fine tune it some more then I'll be done. 17-18psi and 400+ whp was the original goal for this project.

what was the hp?

[BlueRB240]

@nicholasliz0420 390whp@7k where I hit the fuel cut. it was about -4deg less timing than I had last time I did 398.

Did you set the TP limit to 255 ?

[BlueRB240]

@louiswun yeah turns out the maf piping for the blow through might be too small. I have it in a 2.75" pipe, going to make a 3" pipe for it. This is a Ford Lightning Maf.

keep up the good work and i hope you can make over 400hp!
