With the mods you have you should see some peak gains with larger mid range gains. Sometimes the ecu's have adapted really well and gains are initially hard to see but after it is tuned and the targets are adjusted you should feel more responsiveness and more linear power as those targets are hit.
We will provide you with a before and after dyno sheet as well as you ROM file if you request it. We feel the ROM is yours as that is what we are being paid to provide you with. We are the most experienced UPREV tuner in the northeast...
Give us a call if you are looking for another pro tune.
