Awesome! We have another member on here that did a couple dyno runs with the Stage 2 and down pipe, so we are just waiting to see their results as well.

 

Stage 2 tune and downpipe are on their way. Soon as they are here and installed I will dyno as well. Gotta find shop near by in NC that has a dyno.

 

You'll love it!

 

Anyone with the tune and or downpipe have any codes thrown? I got a cel code p0420 the other day. cleared the code and have driven 150+ miles without the cel popping back up. Going to give it another 100 miles hopefully it doesn't come back on

 

I have the Stage 2 tune and catted downpipe with no CEL. That code could be a faulty 02 sensor. Are you running a tune and downpipe?

 

Yes sir, Ya i believe so too. we'll see if the cel comes back on. so far so good

 

Definitely keep us posted. It weird for a O2 sensor to go that quickly.

 

I had a CEL when i was running stage two without the addition of a downpipe. The CEL was able to go away on its own after about 24 hours. if it keeps happening I would try adding a spacer to the downpipe sensor before looking into actually replacing the o2 sensor

 

yea thats a good idea! I'll do that before replacing anything. I have driven 200+ miles since i cleared the code and nothing has popped up. Everything seems fine for now

 

Question,

I plan to getting AEM CAI for my is200t, and maybe a F-sport exhaust.
Is a tune required? Do I need a new ECU for that?

Thanks,

 

No, you can add those parts with the existing OEM tune.

 

A tune isn't required for such bolt ons. You'll have more usable power throughout your powerband but you won't see much in peak gains. If you want to see higher peak gains then you need to get tuned

 

Not really looking for peak gains, more usable power is all I want.
I just wish there was a way to improve power between 2k-4k rpm.

 

If you are looking to increase power in that range, try looking into a piggyback system like Burger Tuning (BMS) or TOM'S, Its an easy plug and play device. If you are really looking for power gains then you'll need to get a down pipe and ECU re-flash from TTI.

 

TTI Stage1+TCM on the way. Try to manage Dyno to have a visual comparison ;-)
Keep you posted,
