I have a Ej1 with a gsr swap. Trans etc. Has header intake ,,exhaust, edelbrock manifold. And other goodies not related to the motor. Anyway it has gsr ecu my question is would it be worth getting the p28 and getyini tuned. Thanks

 

what do YOU think?

 

Yes it would be beneficial to at least run a chipped engine computer and or have the vehicle properly tuned.

 

Tuning being the key word

 

IMO an intake, header and full exhaust would benefit quite a bit from a tune.

With and intake manifold + TB, then even more-so.
