Back from the dead
Had a good RR day out at Bills yesterday and was hoping to maintain or improve upon the previous figure of 325bhp but the butt dyno had a feeling this may not be the case. Over the past few months I had added a SEM intake manifold, decatted and improved upon the wmi setup.
Recent logging had shown an increase in cf's but nothing major. Unfortunately I only run in 3 rd on the road due to safety but when she was run in fifth on the dyno the lack of tuning to compliment the mods showed itself in increased boost and very high CF's
. Only 314 bhp. A rooky error of one I know better. Once home I disconnected the n75 and connected my ebc to control boost (constant 21.5 psi) and dropped timing using lemmiwinks by 2 degrees and hey presto max cf's of 3's at a timing advance of 22 degrees at the red line. Lesson learned.
Its such a fine line of boost verus cf's since an increase of only 1 psi can be seen by a corresponding increase in cf's. The joys of tuning.
