Whats up peoples,im kind of stuck here i just bought a 94 EX eg coupe that came with a d15b. Im having problems trying to pass 5500 rpms,im redlineing at that point and i taught that motor could handle 6500 to 7000 rpms,but that's not happing. Vtec engages at 4500 rpms and just around the corner is 5500 rpms,so im like wtf...So i called my boy and he brings 3 different chipped p28's, with different programs skunk2,mugen,spoon. Plug them in test drove it, and i end up with the same thing cant go pass 5500 rpms.Vtec still engaged at 4500 rpms but just a lil bit harder though,and im also running a p28 in my car.So my boy say's that the motor probably came with a dx dizzy not the ex dizzy he said maybe because you are not redlining further because im not geeting enough spark he also said that my wiring could have a problem with it, i told him that im not throwing codes,and my oil is leveled.So what im asking is can anybody help me with my sisuation or if you expericend a problem like this before. Please help me out sought out the problem. Thanx

I dont think this comment helps him resolve his current issue unless you have a good motor to "give" away.
