Slight hesitation when coming on boost - R33 GTST
Hi all. Since I've had my Skyline I've noticed that often when coming onto boost (from 1/2 throttle or more) from a reasonably low rpm (under 4k) there will be a slight delay in the power coming on.
It's a 1997 GTST, only engine mods are pod filter, front mount, yellow jacket coilpacks and MBC. Fresh BCPR7ES spark plugs gapped to 0.8mm.
I'll watch the boost gauge and it will make 10 PSI (my set boost level) but won't really shove for another second or so. It kind of stumbles for a second before it remembers that boost should equal power. It doesn't splutter like with buggered coilpacks, it just kind of doesn't respond properly for a moment. It's not the delay from the boost itself that I'm feeling, there's definitely a delay between boost and power. That's not right, surely?
The only thing I've really tried is replacing my fuel filter and cleaning the MAF with some electronics cleaner. I'm thinking either MAF or fuel pump. Any ideas?
