I just got tuned at Prime Motor with Jr. Below is the Mustang dyno chart of my best run. Max boost was at 22 psi for this run, since I forgot to bring the thicker spring for MBC to go to 25 psi. Any thoughts?

252 whp/ 237 lbt

Mods:
3" TBE, with Test pipe
stock intake with high flow air filter
255 walbro lph high pressure fuel pump
maperformance licp
hallman MBC (gonna go EBC next time)
93 octane

 

Be nice to see her run again on good fuel, 98 octane or better I think it will pull nice numbers not bad for 93 considering there designed for 95 minimum I'm guessing it was hard to advance due to detonation with the low octane fuel, but grats all in all would feel great to drive

 

those mustang dynos break hearts! good numbers for minimal mods though, a tune definitely makes a stock evo wake up!

 

The mods are minimal since the car is my daily driver. Not trying to kill my mpg.

 

Our octane in the States is measured differently, 93 is good pump gas.

 

Yeah are pump 93 is the same as your 98 over there , they just use different numbers as is RON and MON.

 

9.8 or 10.5 hot side? Mileage on the car/engine? The numbers seem alright for not much higher than stock boost on a Mustang dyno.

 

Not sure which one, assuming the 9.8 since my car is a 2004 Evo 8 stock turbo. Car has 13,000 miles and stock 4g63 2.0L.

 

looks right on the mustang dyno.

 

13k? Beautiful. I'd love to see some pics!

 

Not bad for the small amount of mods

 

Actually, USA uses AKI (anti knock index), which is:

RON (research octane number) + MON (Motor octane number) / 2 = AKI

Overseas, they use RON.
