Race cams(c20xe)

[xet4]

Hello friends,
5 months ago i installed SBD 304/295 degree 11.9mm valf lift cams
but my problem is the exhaust cam is short there is no L shape for hall sensor reading
i installed them but when i push the accelerator the car was stopping(i was using motroic 2.8 ecu and chip) and the car goes very bad(looks like 150hp )
afr on full throtle 13
on part throtle 14-14.5
i have not got taper throtle
my c/r is 12
is hall sensor can efect it?
now i am using aftermarket engine management and i dont need hall sensor(semi-sequantial and waste-spark ignition i have to use because i have not got hall sensor on my sbd cams)
is the car going to run with no problem beacuse when i use original engine management the car stoped and when i want to run i have to push throtle %30-35 and i have to push very slowly the car couldnot go nearly 3000 rpm
now i have aftermarket ecu can i use my car easily or not?
Thanks
