this is the 5th log after installing perrin 3inch intake, with their supplied maf scale... worst anyone has ever seen??
i figured id give it some time to learn after watching the first logs numbers creep up, but it just got worse and worse,
mods on car are crawford bpb, tanabe catless fp (possible its leaking ? did some reading and this crazy of ltft can be caused by that ?) and a catback,
any pros out there care to share if they think its a tune issue or hardware problem? hadnt noticed any leaks in the exhaust, and i was pretty thorough with the intake install, everything was tight and secure, so yeah, is the perrin scaling really this bad ???

1. The perrin supplied scaling is not very good in car I tried it on
2. you rearly do need to make sure you have no intake or exhaust leaks else this will cause high LTFT, exhaust leaks usually give you high positive trims at lower, which you dont have.
you either need to rescale maf yourself see links at bottom or
I suggest you try @
Wayno s3" maf scaling, knowing wayno it will be pretty good.
Make sure you use the 3" perrin if you have that , the spreadsheet below has both 2.75 and 3
