Car is 2002 RSX-S with Hondata reflash #4, AEM V2 air intake, stock exhaust.. stock everything else (on the motor) actually.
When I'm on part throttle (maybe 1/2) accelerating medium/hard it feels like there's a power dip at about 5200 rpm.
Under full throttle it feels fine, pulls hard all the way thru the power band, it's only when accelerating moderately at about 1/2 throttle.
If I understand it correctly the #4 reflash has a VTEC "window", it will switch at 5200 under WOT but wait until as high as 5800 under part throttle. So does that mean at say 1/2 throttle it would switch over at about 5400-5500 rpm? If so then it seems like the power dip is right before VTEC. Is this indicative of restrictive exhaust, or something else?
