These are designed for each specific car now from what Neuspeed is telling me- Neuspeed is owned by a larger company that has been around and making chips for like 20 years. I think these do more then raise the PSI "now".. however I'm not 100% sure and still trying to work with them on a date for the S3 one. I have always had the best experience with GIAC tuning with the remote. So Smoooooth.

Neupseed I had on a 2004 1.8t and it was pretty jerky.

It intercepts the MAP sensor to make the ECU believe the car is underboosting, and it thus forces the turbocharger to work harder and make the advertised boost increase. Normally, a piggyback would also intercept other sensors, such as the rail pressure, to make the system work together. Since this module only intercepts the MAP sensor, it relies on the wideband O2 sensor to realize that the ECU needs to inject more fuel. It just seems like an incomplete approach to me, but I can't say that I have much experience using this specific unit.
