This summer I'll be leaning towards a max 93 octane tune for 550ish + whp.
Any suggestions or upgrades I should do before getting the tune? Already have a strong idea, but like to get feedback from the community. If you like to see my specs just click on my build log in my sig.
I'll have a fuel return, using 255 walbro,650cc injectors, boost controller, and ATF gauge using uprev.
Thanks.
