Hi out there just joined very new to the modification seen after buying my first evo iv.Just bought an Apexi Boost controller .Just wondering if you guys know what the standard boost runs at on an evo iv and what is the safe upper limit for boost.All new to me so hope i've used the correct terminoligy.Any other ideas on mods would be greatly appreciated.

.7 to .8 on fully std.
Safe I'd say 1.1 or 1.2 maybe
Early ones had a fuel cut at 1.7!!! Later ones 1.2.
