You need a Boost controller to get anything above the wastegate spring pressure. If WG is 7PSI you will get 7PSI you need a controller to turn it up, the E-Manage will not do this for you. (nor will any other EMS) With the GReddy kit you will need to run around 11-12 PSI to achieve 300WHP. If you have a Catalytic Converter or a stock exhaust, don't expect anything over 280WHP. (If that) If you are planning to run more than 10 PSI buy a new MAP sensor now. Unless you want to pay for another tune.

If I were you I would get a new MAP sensor and an Electronic boost Controller (EBC). When I got mine tuned I was still using OEM MAP sensor. I was running 13 PSI, But as soon as VTEC kicked in my boost dropped to 8 PSI. If I ran a bigger MAP sensor and an Electronic boost controller I could have easily made 320WHP. Instead I made 285 WHP. The problem with the GReddy kit is that it cannot supply enough air for VTEC engagement without an electronic boost controller. When an EBC sees the boost drop it closes off the pressure to the wastegate more letting your boost stay consistent. Meaning your power band won't dip down and then start climbing again. Like this:
