safest mod(s)?

I am getting anxious to mod my 335, but I want to start slow. I know all mods have some element of risk, but what should I start with as a low level, low power increase mod? I may move on to bigger and better things eventually, but I need to crawl first.

I know intakes are not very effective and cause arguable power increases, maybe even decreases. I'm not interested in sound and cosmetic mods, only power increasing mods.

Any Suggestions?

Many thanks.

Get yourself some Stickers, they have to add a few HP...

In all seriousness, hmmm why don't you start off with an exhaust system from HKS or AE (or if you want to stay within warranty get the BMW Performance Exhaust)

A tune will work wonders (although that's not a low level mod) Unless you go with something like the JB+
IF you want a full blown tune either go with PROcede or JB3...

Working on your suspension will improve your ride (although it may or may not make your ride faster) but you'll be able to take those turns at a higher rate of speed.

Might look into those Pulleys that Roozie is talking about on the forum here:
http://www.e90post.com/forums/showthread.php?t=293350 At a little over $200+ they aren't a bad investment...

That's just my .02.. OThers will chime in as necessary, or they might just flame you and say use search...

JB3 on Map1 Very safe, no codes and when you decide you need more power its a map switch away

I'm thinking I might try the JB+

I just have no experience with tuning and it makes me a little nervous.

I'm gonna get some hardcore stickers and window decals that add at least 20hp each.

Thanks for the tips.

The thing about that JB3 is I don't want to install and remove every time I go to the dealer. I could do it with the JB+.

The JB+ comes with a 6-month free upgrade policy so you can switch to the JB3 for full credit so that might be a great way for you to start.

PM me for more info if you are interested.

I second that. Start with JB3 right away and a BMS gauge if you can. MAPs 1 to 3 are perfect way to start. Stock like drivability and smoothness, just with more power. Got used to the power with time?, just up the map.

I find it actually easier with PnPs then brake your hand while reaching to the TMAP.

It's tough for me because I live in a apartment building. Not very easy to take my car apart and remove ECU base tunes.

GIAC flash is probably the best bang for the buck and cannot be detected by your dealer.

Keep the mods subtle and don't be threatened by modding - this will ruin the experience what is possible out of your BMW's powerplant.

Poor Excuse... I live in a Condo in the bronx (no parking lot attached or underground), and when I had my accord, I did all my mods out on the street... And If I were to MOD my 335, I would do it on the street as well...
