So I spent today cleaning the car and had the idea that removing the back seats and trims would save me a bit of weight until I got them out and realised they actually weigh less than my puppy lol, anyway I fitted a boost gauge while I was on just to keep an eye on things and it's seems I'm boosting at 17/18 psi, is that normal for a 260? Small mods like k&n and cat back exhaust nothing major.

14.5psi (1.0 bar) is standard. However, with induction kit and exhuast, 17/18psi (1.2 bar) is norm. Note that on a cold day you might hit boost cut (about 1.3 bar),to get round boost cut you need a remap.

Breathing mods will cause boost creep like you have found.

Always a good idea to get the fueling checked. Any place with a dyno will do a power run and check fueling for approx £50. Or if someone on here is local to you they might be able to check for you on a wideband.

get yourself a wideband then you'll always be able to monitor the AFR, normally cars are a little rich when straight from the factory so your probably on the limit now, as said would be worth getting it checked over by someone local

Well I'm getting a remap next month so could it cause me a problem between now and then?
