Hi everyone, my r32 has an rb25det conversion done by previous owner. I have owened it for about two weeks now. I have done the usual services, oil change, auto trans flush and new spark plugs. Now the thing I am noticing is when under hard acceleration it wont boost past 6.5lb or seven if I'm luckily, its okay reving through the low to Med range but as soon as the revs get high it feels like its spitting or missing, when I take my foot off the the gas a little it kicks back in, slightly. I have checked all vacume lines I could see, which are all silicon hoses with no ties? The coil packs are stock as far as I can see but I would like to find out if it could be more basic before I fork out the cash for new coil packs. Any help would be great or directions to similar threads.
