What sort of power can I get from e5 gsr

[And@fcm]

after you've fitted if possible do a boost leak test and also don't forget to switch the boost controller to one of the lower settings first (ie 2),then change it to 3 and then 4 and just check what the max boost is with each one, as the duty may need adjusting, drop us a bell if you want a more detailed explanation.
