You need to take vehicle for a dyno tune to get it nailed down 100% correctly. Mail order just can't get it unless you are providing some data logs so they kinda know what to tweak on. Even then those engines and what you have it installed in and what has been done to it needs to be seen by the person tuning it so they can drive it and get a really good feel for what you want versus the problem you are experiencing.

 

thanks for confirming info. I did find a guy who can do the job. Yeah, the mail in the ecu gets it close but not to the specks for the machine..
