Motor Chugs when step on Accel cable also Tacho is acting funny

This isn't my car, it's an MR2 with beams engine.
I am not able to look at it as i'm in tas again. :(-
But i'm told the motor is chugginf when you press the acc down. Instead of the engine responding and driving faster it is as if it has no response and then kicks in.
I suggested getting the TPS recalibrated as installing the beams engine could of bumped the TPS position. Any other reasons to look for?
Also another problem, and one that i unfortunatly can't look at. the Tacho needle will fluctuate as if it's getting a signal from something else. acts crazy going up and down. Does this sound familiar to anyone thats done an engine conversion? Is it simply a wire connected to the wrong place? Typically does the tacho run off 1 wire from the ECU?? It seems to me it is getting the signal from something else. Is there a common ECU pin for the tacho? If so whats it called? or even better what is the ECU pin that drives the Tacho on a caldina blacktop beams engine?

May be unrelated but it happened to my ra65 when i installed a pod filter. After a while it just went back to normal.

Well i can say it does have a pretty restrictive air intake. but i'm pretty sure thats not what is cuasing it.

sounds to me like the timing maybe a tooth out. did you do the timing belt?

No just put the engine in as the previous owner said it was all setup to go striaght in no messing around needed, so i didn't bother to check the timing. And come to think of it i don't know how you would do the timing on these beams engines where they have a coil on each spark plug, can a conventional timing light work on these setups??
It wasn't chugging when i was driving it. seems to of cropped up after i left.
