What would be a ball park figure for performance (hp/torque) I can expect with JB4 G5 map 1 on an N54 engine (RWD, 6AT) with a BMW performance exhaust and a
Wagner intercooler and just regular 93 fuel?
Is upgrading the intake worth it in this case? I'd consider dropping in another intake but from what I've seen the DCI make those typical turbo sounds (blow off etc.) which I really don't like.
I'm only interested in map1 as map2 requires downpipes which I can't do here. Map5 seems to be too inconsistent from what I've read and I'd rather have less power with stability over more power with inconsistency.
