map sensor?

I know this is not part of the answer. I am just installing a map ecu on my supra bpu.The car is having hesitation. Do you have any tables you could send to me to try? The one of the internet for 550cc injectors is not quite working enough.

 

There is hesitation from pulling off the line in drive and reverse and then again at 1500rpm and 2500 rpm.

 

Thanks for any help

Just wondered if any body had experienced similar problems, I have noticed that if I plant the throttle to the carpet at first it takes off then a moments hesitation and by the time you notice, it has passed and launched its self and pinned you back into your seat you then have to hang on as the speedo climbs rapidly.

I'm going to put a set of plugs in first but what about Manifold Absolute Pressure or throttle position sensors?
