is there any other way to do ignition timing??? cos im pretty sure that ignition timing might be one my problems, i thought that sorta thing can be tuned without anything additional. one more question, is a piggy back ecu more than a s-afc??

i dont plan to upgrade the turbo anytime soon, or the injectors, i got quoted $600 for an s-afc, and $700 for a s-afc 2. do they both do the same thing, cos if i dont need to spend the extra money then why bother whats a ruff price for a piggy back ecu??? and what can it do that a s-afc cant??? thanx

first of all, i'd like to say hello to all of you in the forums, the info here is priceless and has helped me at many times. i have a 1993 r33 gts-t with the following mods: front mount cooler, 600 by 300 by 76mm turbosmart type 3 plumback blowoff valve turbosmart dual stage boost controller k and n pod filter with cold air intake hose from bumper thasts about it for performance mods im currently running just under 10psi and have tried to go more but the engine pings and splutters and it sounds like the engine cuts out for a second or 2. i called a guy that specializes in turbos who has a dyno and he said a s-afc would fix those problems along with a dyno tune. what do u guys think?? and whats the difference between the s-afc and the s-afc 2?? thanx in advance
