Hi guys - I haven't found a tuner nearby that I trust with my car, so what's the best I can do mod wise with off-the-shelf maps?

Currently, I have an AccessPort, a Perrin panel filter and a Perrin stg 1 map. What exhaust components (or other parts) can I add to safely squeeze the most juice out of a stage 2 map?

Any advice would be much appreciated.

 

Someone has a post on here about a OTS map from Perrin. It was pretty decent but nothing can beat a custom tune. We ended up with 324 hp and 328 tq from 297hp and 30x tq with OTS map.

Just follow what the OTS map says for upgrade is my recommendation if you're not wanting a tune.
There has been a few Evo X and ralliart tuned locally.
