I am trying to figure out what is going on here. I have an ITR and a GSR ecu for my b16a in my 97 civic. I noticed that with the itr i have better low RPM response and I do definitly notice vtec but it is not as powerful in vtec as the GSR. The GSR is really gutless in Lower RPMs but in vtec it abolutely screams. I am not sure why there is such a differece. You would think that the ITR would pick up in vtec the same or faster than the gsr. Is this suposed to be this way or is my car not running right? I guess the better response in lower rpms on the itr make up for the slightly weaker vtec but if there is anything i can do to make it run better i would like to know. Let me know if you have any ideas.
Thanks
