Hi guys, My friend is thinking about chipping his 335. Neither him nor myself have much experience doing so, and were wondering if you guys could give us some advice or point us in the right direction. We're in the UK if that's relevant. Thanks!!
The good thing about dinan is you get a warranty and I believe you can work with the dealership and it won't affect that warranty as well. Check out e90post.com. Theres a couple performance mods to get way more power for probably less money than Dinan. Just not warranty help that I'm aware of.
The options are essentially: juice box and vishnu without warranty. Dinan with warranty. Dinan option is expensive for the power gain, but at some point it is overkill. I had a 335 without chip, and I friend of mine installed the Dinan chip on his own, which he loves. Personally, if I had done it, I would have used the Dinan chip.
A buddy of mine has Juice Box on his 335i, he has the JB+, I didn't get to drive it yet, but I hear it's amazing now.
