I've been following that thread for a LONG time. I haven't tried anything tho as I do not have a tuner license. Sending that to your tuner my make things a little uneasy. Some of them think they know everything. I would think about getting the tuner license and doing it yourself ?

Fixed the throttle. Just a copy paste from the link I posted earlier. Car feels more torquier. I only tested 1st and 2nd though. Will update on drive back home if traffic and weather allows me to test it out some more.


Edit: Still very driveable, not jerky. Better response and more usable torque. Still have to test it a bit more in an open road.

Yep, this sums it up. I had a friend tune mine, and without any breather mods (still waiting for my FI exhaust - 13 weeks and counting) the car is completely different. Most noticeably in 3rd-4th in the 4200/4400+ rpm range.

Looking forward to throwing the Gen3's and the FI exhaust and retuning it!

Are you planning to run stock CATs after your FI exhaust and Gen 3 upgrades?

Yeah, for now. Maybe that'll be round two of upgrades sometime next summer. Are you on stock cats?

so i was planning to tune my car soon. as of today i have 118,060 mils on my 2009 G sedan. I noticed that the car doesnt run as it used which is understandable. My current set up is:

Invidia CatBack
Invidia HFC
K&N short CAI
cranck pully

I'm not looking for big gains, but more of a smoother ride and better response when i hit the accelerator... question is, do i take out the k&n CAI and put the stock ones back? would a tune make a difference at this point of miles???

If you have all those mods your car is without a doubt running lean afr's. You would notice a really nice change with an increase in, line pressure , addition of fuel and increasing throttle sensitivity. And all these can be done by simply e-tunes and no dyno needed. With your location what I'd do is either buy Uprev with the cable and have the seller tune me in to acceptable performance parameters OR.....I'd purchase Uprev with the cable and also get the tuner license ( Which is what I have ) This will make it so that when you do get your base tune and it's tuned as well as an e-tune can , you turn around and take it to a dyno for final tweaking. With the tuner license anyone with a basic knowledge of tuning can make adjustments and also the car can be tuned by a tuner on the road in real time. It also allows you to monitor your engine in real time, turn off codes , read codes and perform fuel resets and all manner of interesting things.
Here's a screenshot of the parameters I use in one of my log files for a 0-60mph run earlier this week.

Nope. I have FI resonated HFCs. Just figuring out what to do about smog since I moved to California recently...

Realistically, the best mod is to just get gears. That will give the most noticeable increase in performance for about the same cost as a tune and dyno time. Funny that no one has really mentioned ecutek, they actually have full timing control where the car will always run the timing that has been set by your tuner. This will in turn cause the car to run more consistently. I have had it on my car for about a year now and have no complaints. Takeda Cai, ark exhaust, 3.90 gears and ecutek tune has completely transformed the car.

Well you have to remember gears aren't an option for everyone X guys can do gears, So UPREV is the choice for a tune. ecutek I was and still am not sold on :/
