acceleration problem with v70 t5 1998 with ipd sport package V70-XC70

Hi everyone, i have a 1998 v70 t5 automatic and ive just installed a brand new ipd ecu and catback.I have 190 000km on the car and it runs great but since i got the ipd package installed the performance seems not very consistant like the 0-100km or 80-120km sometimes theres a difference of a second.Some days the car pushes really good and sometimes it doesnt.Could it be my o2 sensors (there are the originals) but i have no codes or maybe the catalylic converter.....The acceleration sometimes has hesitation.The hole ignition system had been changed.Thanks for your ideas.DANIEL

    Hard to say what problem is. It could have existed before, but the added power now makes in more noticeable. Have you had all engine codes checked?, that would be my first step. If you have boost gauge, does the boost fluctuate? How about vacuum is it up to snuff? The problem could be boost fluctuating due to loose piping or worn diverter valve. Does the engine miss, hesitate, or power is just not there?

      Thanks wills for your answer and yes the power is there but sometimes it hesitates.The car was recently checked and there was no codes but i think you have a very good idea about the vacuum lines ( for a leak check ) , i dont have a boost gauge but i was thinking of changing my turbo piping for a bigger one so it might solve the problem.Thanks again Daniel.
