i dont know the difference but the p72 chip seems rediculous to put in... 4500 rpm vtec and 10000 redline. wow. I dunno about the p73 but if its anything like that i wouldnt consider puttin that in w/o at least valve spring upgrade and arp rod bolts.

P72 is the GSR and the P73 is the ITR I think.

P72 controls IM secondaries while the P73 doesnt, different rev limiters and thats as much as I know about them.

P72 is like 8200 or 8300 fuel cut I think, isnt it? P73 must be like 8500 or so?
