Stage 2 chip Q

[MarK4]

Hi, what is the absolute maximum boost you can run on a stage 2 with T28, front mount and the usual mods providing everything is working properly and you don't mind running the injectors at full stretch?

Its difficult to say. All engines start to det at different boost pressures. You might be able to get away with anything from 14-18psi.

Due to the fact that you would need to retard the ignition if you want to run high boost, you need to weigh up the balance of off boost performance and peak power.
