I can tell you this....If I put the Standard ECU or Impul on my car with the turbo I have on it its a Fat Black laggy POS.....4,800rpm before boost starts to climb. With the Nismo it was full boost by about 4,200rpm before the tune.....after the tune full boost by 3,200RPM and Cihan pulled some timing out because it was too reactive.
Kickdown has also been played with!
oh and I can do more than 171.5km/h.
I'll lay London to a brick that if a Nismo came up on IM you guy's would be all over it!.....it's the best plug and play mod you can get!...snipping the wire just let's you do burnout's!....well maybe not for Aaron
