    what power increase would a remap give my e46 316ti compact??

    also ive heard its possible to do different remapping, for example to give a car better low end torque, is this right??

    Gains are not huge on any small normally aspirated engine. More low end torque is really on diesels. 10bhp and approx 15nm of torque is the most you will see on this engine.

    On a ecu controlled engine you don't map for power in rev zones like old school tuning. A mapper will alter the fuelling and ignition timing thru the entire range to give the best results, hard ware alterations are going to give zonal changes more typically.
    Stock ecu may not be great to map tho side by side with something like a motec. You will be as lucky as a lotto winner to gain 15bhp on a 1800cc NA engine unless you have hardware changes done. You may gain 3mpg and good response under foot tho, real world performance not numbers to chat in the pub. Don't expect the world to change tho from a stock NA engine remap but it can make the car far nicer to drive.

    i've got a 316 compact not as new as yours mate but when i looked on remaps it says it takes it from 102bhp to 113bhp. not worth the money for an extra 11bhp

    All depends on what you want mate,
    10bhp in a compact is a good gain... far better pickup at low rpm and more eager through the gears...

    cheers guys, some good, honest advice there! not going to waste my money!

    going to invest in a good quality air filter though to try and get a bit better throttle response!

    a good service with decent oil and plugs, clean all your breathers, some times disconnecting your battery for 20 mins can reset the ECU to factory settings IF it's a learning ECU like on the latest VW/SEAT's
