i need some help witch would be the best for a daily driver baja any info will help

Fuel injection wins hands down. If it is stock engine just use the factory set up, keep it and use it.
With a stock cam or a mild performance cam, Dual IDAs are a nice performance upgrade but lack chokes, altitude compensation and won't work well at slow engine speeds in rough terrain. With FI you can load the engine down and it still pulls away.
Cost wise if you are resourceful with Mega Squirt, FI can be competitively priced with a new set of carbs and jetting costs.

i still have all the fi stuff so looks like im going to half to clean it and put it back on. i also herd that you can use 80's bmw comp,injectors,and throttle body for better performance.any tips will help

I fixed a lot of FI but did not do performance upgrades. Since BMW had larger 4 cylinder engines that should work. Head over to the FI forum on shoptalkforums.com. There is alot of information on tweaking stock systems and alternative programable ECMs such as Mega Squirt.
