Stock VTEC X-over is around 56-5700 rpms. You may have a chipped ecu. X-overs that low create a major dip in hp at the x-over point. I suggest checking the ECU and if it is chipped get a VAFC to tune the fuel map and push the x-over back.

"the GSR's VTEC cross over is at 4875 and the secondaries open at 5750. I have a stock P75 bin on my computer so I know that the info above is correct." --whtteg and yes the p75 is the ls ecu, but he goes on to say, "I meant P72 sorry This was one of those cases were I was doing way too many things at once LOL"
http://www.automotiveforums.com/vbul...d.php?t=163308 whtteg is a really knowledgeable guy and knows his stuff. So he's most likely right on this one.
