Evo 9 - GT3076 power
This was a retune as the customer added some Mivec cams to realize the true potential of the GT30.
He wanted to move away from Meth and stick with straight octane this time around. We retuned the car on 91 octane and then moved to 104 octane unleaded.
Car made great power, with great spool on 91 octane @ 22.5psi, 10.9-11.0 AFR
350whp / 285wtq
Moving to 104 octane, I ran into the limits of his stock Evo 9 metal BOV. No matter how I adjusted the MBC the car would not boost any higher than 26psi and would drop to 24psi or so up top. I believe this car has another 15-20whp in with a BOV that could hold the boost this turbo can put out.
That said it still made pretty good power!
26.5 psi peak to 24psi up top, 11.4-11.5 AFR
396whp / 330wtq
+46whp / +45wtq peak over the 91 octane tune!
Dotted lines are 91 octane, solid is 104 octane:
