88 s4 10th ann need help tuning please
88 10th ann-
mods are.......
-walbro 255lph fuel pump
-550 primaries, 1000 secondaries
-fcd
-all emmisions removed
-6 puck clutch
-custom t.i.d
-knighsport turbo upgrade on new s5 turbo
-electric fan
-throttle body mod
-rat nest removed
-apexi safc2
-blitz bov
-recenctly rebuild motor by bruce terantine(s/p??) in fuquay varina
i think thats mostly it..but my question is im still getting a studder when the secondaries are coming in and i was wondering wouldnt this be because of the larger injectors be hitting an extrenemly rich spot? and how harmful is this to my motor to be running this setup untuned?

the studder is a common problem in 7's. new rtek 2.1 fixes it. only way to fix it other than a standalone
and dont tune it until you get a wideband or dyno it with a wideband
you'll just run really rich. wont do any harm other than to ur wallet
