Stock GSR B181c engine:

1) Skunk2 (IM pro-series + 68mm throttle body)
2) JDM dc header 4-1
3) Blox High flow cat
4) Tanabe G2 exhaust cat-back
5) 3" air intake

What's untune dyno number?

If tune, which ECU should I buy?

Thanks for your help!

 

the ecu u can us is a p28 out of a civic that has vtec or a p72 that comes out of a dc ether both can be tuned on chrome

 

4) E-Racing/Bench Racing/Guess my 1/4 or HP
There is no place for it here, it is not productive, frequently leads to arguments, and is generally pointless. Go find a dyno or a drag strip.

 

about 210hp....240 under vtec load
