could it have been mapped??
hi all , maybe a daft one,
i have a pal whos got a type r scooby not a lot of mods , filter, exhaust , fmic , about it really , not mapped !now his car runs like a bag of s**t,
another friend with a uk2000 , same mods , not mapped , guess what , runs like a bag of s**t !
now mine ,
uk2000 decat , 3" exhaust , filter ,440s , fuel pressure reg , fmic, cold air induction , ajustable boost controller, hks fuel cut defender , and few bits, NOT MAPPED YET! but going to be so dont give me the speach , LOL 
, however every mod i do the car feels quicker and more responsive ( dont no why?) could it have been mapped before i got it do you think 
as it keeps running better , ( no its not in my mind!) as i have been in all cars ,
what do you think guys other than getting it on a rolling road i no its difficult
cheers chris.

It may well feel faster, but wont be running as well as it could.
Obviously, yes, it could have been mapped, but for it to have been mapped to your current spec and work well would be very fortunate indeed

Just what I was thinking when reading the OP.
No speech, but when you come back with a melted piston...
UK Scoobs have different maps to imports, fuelling is one of the differences. Were your mates cars mapped for UK fuel as IIRC Jap fuel after 97-98 (Tony burns will confirm) was 100 ron, so not even V-power, Tesco will be sufficient, unless adding octane booster.

There could be many reasons, but the most likely one is the FMICs. These force a number of changes on the car - the standard airbox is usually replaced for an induction kit which screws with the airflow over the MAF. This is made worse if the stock dump valve is replaced by a VTA or even deleted (which causes reverse flow over the MAF when off throttle). Also, the long lengths of pipework can increase the response time of the MAF.
A remap can fix the response against most of the above issues (except the reverse flow - can't map that out!). It sounds like whatever you've done has mimicked the standard flow closely enough (perhaps through luck rather than judgement?) to be okay. You are probably running richer under boost due to the 440s and the FPR. This could be costing you a bit of power but leaving the car running okay / safe. Or it may not be, you never know without measuring it!

basically your telling me ive just been lucky
and yes i will be getting it mapped , it just goes to show not every cars the same !cheers chris.

The VTA will cause a rich pulse when it activates, as you are losing air - but this is usually as you step off the throttle, and it doesn't have a huge effect on how the car drives (although it can theoretically contribute to bore wash etc.)

Yep, the FMIC usually requires an induction kit as the pipework normally goes through where the stock airbox lives. But however it is fitted, you're getting nice airflow over the MAF.
