Bout to crank up the boost in this thing...

Going from 18psi to @ 25 via street tune (DiabloSport Predator)

Soooooo, we were only able to crank the boost up to 20psi because the previous shop rescaled my 680cc injectors for only 18psi...

At 22psi we had to add waaaaay too much fuel, so I decided to wait and get the injectors rescaled so we wouldn't have to add/subtract as much fuel through the DiabloSport...

Good thing is that the car has 0 knock and the AFR's are flat at 11.5 up until 5400rpms...

At 5400rpms the AFR's jump to the low 12's due to the incorrect scaling...

Not to nitpick (before @kronin323 comes in) but an AFR of 12 is less fuel than 11.5
Of course it is...I didn't say it wasn't...

At 5200rpms, the car leans out into the 12's...

I "could" go into the DSP and add about 7% fuel from 5000-6000rpms to bring it back down into the 11's...

Not sure what the timeline is for a rescale, so I may have to drive this slow car at only 20psi for a few weeks...
