Hi mate
What do you mean that you "never run on regular gas"
With Hondata you can run on 95 Ron if you want .. the cheap stuff.. or you can still use Super or opti.
As for the mod, yeah I think its a great mod to get a little more power out of your car.. plus if later on you decide to add more mods, exhaust, headers etc then you can upgrade your hondata to the K20 Pro re programmable jobby
