Can I push more boost with my set up???

Postby Rob3487 » Tue May 05, 2015 5:01 pm

I have a red top sr20 with 35mm tial waste gate w/12lb spring. No boost controller-boost runs off wastegate spring. I'm running MSD 50lb injectors, a greddy intake manifold and .60 trim garret turbo.
The ecu is rom tuned to the bolt ins I have. If I were to get 15 or even up to an 18 lb spring would I have to re tune the ecu? And I'm assuming if have to adjust fuel pressure or would what I have already be just enough for the injectors?

I suggest a wide band O2 sensor so you can monitor AFR. You may discover that a tunable ECU with data logging is necessary when modifying boost.
