Just wanted to let you guys know... the TSX reflash is by far one of the best mods you can possibly do. If you are curious in ANY way: JUST DO IT.
Beware however: Your car will be faster, meaner and pull harder than you were previously used to. Your girlfriend/spouse may not like that.
The biggest gain has to be between 3-6k rpm's. This is all useable for every day driving. When you step on your gas, you're going to feel the extra pull, no doubt about it. While Hondata is tuned for an Intake and Headers, you can certainly have the mod without. I have no aftermarket header, but am still enjoying the benefits of Hondata.
Bang for buck, Hondata is the BEST performance mod.
See my dyno:
Blue line: Hondata + Comptech Exhaust
Red line: Hondata + Injen CAI + Comptech Exhaust
Pretty much Just like a CAI Hondata shouldnt negitivly affect Gas Milage (CAI can tech improve it) however, your gonna want to get on it alot more frequent and drive alot harder, which of course will Suck down Gas
Im from Long Island, I go to college down in PA, prob gonna transfer back up to NY after next semester, Wanna go to Cooper Union (lol good Luck there) or something simular for Architecture, Would be nice to live in the City for a while, though the TSX would have to stay back home
