Ok well i need some opinion on tuning option

I plan on going boost soon on my em1 and i was planning on boosting on stock internals on 7psi

I was wondering what kind of tuning option would be reliable but wont break the bank either.

Could you provide me with these option and how much it would cost

and would like to know you could provide the material.....as in; ecu, chip with boost option, obd2 to obd1 harness.


Thanks for any info you can provide me with
