Hey guys I am in the need of a dyno tune after doing engine and cam mods. I have an 2004 with no O2 sensor ports exhaust. I still have a SERT of 3-4 yrs old when I did stage one upgrade.

My local dealer swears they do not use canned maps and do a custom tune. should I believe this? Is there a way to tell if they did a custom tune or just a canned EPA compliant map. I am not sure I trust them.

on the other hand I have a guru and former forum member from Central Florida who at first said he could/would tune with SERT...but now says he wont and wants to sell me a TTS and tune...

 

Go with Doc.
