Sorry for the late response. Its a first gen. Prefer it over the second gen. I just ordered the FlashPro so in a few days that should be on deck. Question. I'm a little wet behind the ears when it comes to a few things on modding a ride. Would it be worth it to use the FlashPro with just the Injen until I get the header (next mod)? I just wanna make sure I do everything proper.
Hey, no problem about 'late' response.. we all have lives outside of the Forum, no?? I mean, I am constantly online here, but that does not mean i sit 24/7 infront of the computer waiting to reply to threads..
"Green behind the ears' is good. You are willing to learn, and are asking intelligent questions, so no worries what-so-ever..
You get an "atta-boy" from me..!!
Ok, the Injen, in and of itself will not require a "tune".. You would "only" be allowing the airflow BEFORE your throttle to become better (Less turbulent), and louder (unresonated/sound deadend). If you do not change anything on your Throttle and/or Intake Manifold, the amount of air being sucked/drawn into the engine will not change.. The Throttle hems/controls this. You have an 08 so this means you already have a larger Throttle (64mm) than the 03-05's (62mm). Too, your Headers "runners" (Tubes/Pipes), your Cat and Intake Cam is better than the pre-facelift. What the FP can do for you is help reduce/banish the 'lag' caused by DBW, and you can lower or raise your v-tec engagement points. You can also raise your rev-limiter, but be careful here!! The TSX Oil Pump is only "good" to about 7500-7800 rpms.. thereafter it 'could' cavitate on you, not delivering enough/any oil pressure, which could be utterly fatal. I would not change anything on fuel trims just yet.
If you want more info on Intakes, Goforbroke (I believe that was the members Nick) and I had just recently had a chat about this,, It was maybe 3 weeks ago, so it should be easy to find.
There also a few other things you can change, in the mean-time, that will help your car accelerate somewhat better, no tuning required. Lightweight pullies are an option (Though there are different 'feelings' towards installing an non-harmonic pulley on the Crank, like the oem has...) and also your clutch/flywheel can be 'lightened'.. cost's a bit, and i cannot say what the single gains on this Mod is, because i drive an A/T.. Flywheel, ok, but clutch i have not, well not in that sense.. nothing to be done here (on A/T), except maybe 'gearing'..
So young man, I believe i have given you a few things to chew over.. If you have more questions feel free to ask. Most members here are more than willing to help, where possible..
P.S. say "HI' to my Mom in Midland, and My sister, in Mississuaga, for me would you..??
