Hey guys a few days ago i revd up my engine really high on neutral and a couple seconds after i noticed an RPM drop of about 1000... i tried it again a couple more times holding it at around 7000 rpm and a couples secs after it would drop back to 6000.. is this normal on the fds or is this something i should get checked out?
The car is totally stock with exception of the apexi power intakes and no i dont have a boost gauge (yet, im buying one this week) so i cant tell you how the pattern is.. it seemed fine to me but then again... well you know...
so can anyone tell me what that is?
Thanks in advance!

 

Are you sure your not letting your foot off the gas some? And if thats not the case then you might want to get that checked its probably the ecu tho.
