Thanks I'll try that also when I test for leaks and put on a new pipe next week.

 

Your AFR (of ~12) is aggressive for your boost spike. Cold night? Add fuel there. You may be able to get away with a degree or two more up top, but every car is different. Work on rescaling the RPM table from peak load to redline to add more resolution at even increments and a smoother ramp up of timing ultimately to your peak.

The power level is about right, but you still have a few more ponies to unleash and some more safety margin to add in terms of fuel. Timing seems conservative.

I made 279 WHP on a Dyno Dynamics dyno with similar mods/fuel but with GSC 272's at 20 PSI even on my Evo 8 a few years ago.

 

i personally made 334hp/350tq on a mustang dyno on 93 oct with less mods in texas heat. so i would say theres atleast 20hp more to be made, especially if those are dynojet numbers

 

What were your mods ? Thats pretty impressive power on a mustang dyno with less mods then he had.

 

I'd like to see that dyno sheet and mod list at the time.

 

^what he said haha

 

Guess you had meth. Either crystal and you saw wrong numbers, or your engine had meth injection.

 

Yeah I would have to agree to meth. I had similar mods along with a old school FP green running meth and made 348 hp / 350 trq on a mustang dyno .
