Edit: I've now noticed it will do it when I'm sitting in park or even when taking off slowly seems like its missing
Hey,
I seem to be having a few problems with my RB25DET, it usually runs fine no problems at all but it seems to struggle on load.
What I mean by load is if I'm sitting in a low speed and give it a bit when it gets anywhere between 4000RPM and 5000RPM it sounds like it's hit rev limiter and struggles for a moment or two then push itself to 7000RPM-7500RPM which is rev limiter.
At higher speeds such as 100-110KM an hour and you give it a bit it's not as bad but it still has a very similar affect.
I'm not too sure what the problem could be, I've put the engine on a diagnostic program and it came up with no errors. I've had the car rebuilt within the last few months, I've done all the running in etc, I'm running good oil (Royal Purple), good spark plugs, I'm using 100RON with 5% Ethonal (V Power Racing) - however I haven't had it tuned since the rebuild - may this be the problem?
I've tighten everything that I think may have come loose. Any help would be greatly welcomed.
