that will only work on pre 1994 cars that run ews1... 1995 onwards run ews 2 which requires a flash tune.. and the car should be able to handel 7500 rpm however just dont sit at that amout of revs becasue it will casue more damage to the engine

I had this exact chip:

Worked well and car was dynoed to have 155,6 hp and 198 Nm.

I revved all the way up to 7500 on track and nothing broke. But you will stress pistons more due higher stresses caused by larger piston acceleration and eventually they will break. They might last 10 years or they may last 1, it all depends how long the pistons spend time around 7500 rpm. When their time is up, they will let go.

thnks boyracer for your infos, do u have any dyno graphs, this is my daily but i do some street racing, i have a 4.45 final drive ratio .. and it is too short for street racing,
how does your midrange felt,did u feel any drop in power above 7000rpm?
i m really thinking wither to go to a longer gear ratio + pro formance chip or to get this chip and see how things turn out ..

I have used Peter's chip installed into various different BMW (M40,M42 S14) & Porsche engines. He knows his stuff
