Hi new here. I recently got the reflash and it seem like it is not right. I got aem sri, vibrant header no cat, apex ws2 exhaust system, hondata IMG, with the reflash. I dyno it and vtec at 4500 but once it get to 4900 it has a dip and HP is at 190. could there be a glitch on the reflash. I thought the reflash was going to make it smooth cross over without the dip.

probably a combination of the intake and a restrictive exhaust. YOu need to look inside the exhaust and see what he internal diameter is. YOu may be better off with a stock exhaust.

but wouldn't the stock exhaust be more restricted then the apexi ws2.
Piping Diameter - 60mm; Tip Diameter - 100mm

the internal diamater may be more restrictive on an aftermarket exhaust...you cannot always trust everything they say.
