Tune after LTH install
 

I recently got my LTH installed and I know that I need a re-tune. I had an Uprev tune done once before after my intake and CBE was put on. I am trying to get a hold of the place (guy) that did my initial tune, but he has not gotten back to me. I had to drive my car back from Simi Valley to San Diego and have put on about 250 mainly highway miles since the headers. How much further should I push it? It looks as though I will have to go back up to Long Beach or Simi for the re-tune. Am I hurting the car or risking detonation?? Advice wanted. Thanks guys.

fwiw I ran with LTH's and no tune for a year with no problems.

Yea, you already have a tune, so I would imagine A/F isn't too far off.

edit: FYI; use wstar's smooth throttle tables. Put a tuned map w/o it and another one w/ it. I've been driving w/ it and I like it so far.

I will be trying out wstar's throttle map. I'm wondering why so many people before were telling me that I must get a re-tune after the headers since I have already had one due to risk of detonation? Is that a real possibility? Either way, I'm planning on driving back up to LA area Sept. 7th. Now, does anyone recommend Church Automotive or Specialty Z over one another for a quality tune?

^church's dyno numbers will make you happy...

But it's like saying you have a big D when it's as big as your pinky, lol

Besides running with LTH and CBE with no tune for a year without problems, I ran maybe 1000 miles with full breather mods (see my sig) prior to the tune. While this didn't include any hardcore driving there were times of "hard" acceleration getting on the highway.
