Jumper mod only works with a stock pipe. The mod prevents the servo from closing the butterfly valve on the pipe. Aftermarket exhaust+ no valve = no good.

The ECUJumper ModWORKS on the stock pipe and Especially on Aftermarket Slip-Onsor Full Exhausts. Maximum HP difference and gains will be noticedwith the Full Exhausts.We have proven this on the Dyno. Read my other posts on this subject in the DIY section and here but just to recap;
The stock USA ECU on 05-07 ZX6R's slightly close the exhaust valve and shut off the fuel supply ataround 14KRPM for EPA Emissions and Sound restrictions. By intallingthe Jumper, you are bypassing the EPA restriction thus making theUSA ECU into a EURO ECU.This fully opens the valve and adds fuel at Wide Open Throttle (WOT). It wouldn't make senseto close the valve and keep adding extra fuel because this would increase the emissions output of rich unburned gas and definitely not pass EPA standards. I recommend you try the ECU Jumper mod on a stock exhausted 05-07 ZX6R while on the dyno and see for your self. It only takes a couple of seconds to install and or remove the jumper.

try leavin at 8 rpm and slippin the clutch thru the 60ft work, this will give u a better 60ft and also helps keep the front end down bc you are controllin the throttle and clutch at the same time
