Tbh, idc about more power, tuner flash does the job well. I want to see better build quality, better tires, and more durable paint job.
Less than a year since i have my Si, i have couple rock chip, and a scratch from my trash can blown by the wind hitting my Si and my brother's G37, the G37...
Hi, i believe you run the right tune, and the +3psi i believe just for the CVT model.
I'm from US and my Hondata have stock equivalent tune, +6psi ( and sport mode only ), +9psi ( and sport mode only), 27WON turbo with 91 octane, and 27WON turbo with e85 fuel.
I do not the +3psi tune
