I am building an LS6 block and putting it in my 98 A4 Trans Am. I was wondering what kind of tuning would be necessary and who to send my pcm/ecu out to.

 

Your mods and goals would be helpful right about here ______________________ .

 

Mods are going to be............Lid, Ported Throttle body with LS6 intake, Ported LS1 Heads, TR230/224 cam, pacesetter headers, 3in ORY, cutout, and Hooker catback. block will have stock LS1 rotating assembly.

 

Well, then we're just going to treat it like a regular ole H/C setup... VE tuning, MAF tuning, WOT tuning, idle speed raise, DTCs... the whole works will be needed..

It won't run terribly crappy from the get go, but find a local tuner to take care of this stuff.

 

Thanx man i really appreciate it.

 

Back again...Should i send out the PCM while im building up the motor?

 

You should start with your stocker tune and have someone knowledgable be around when you have the setup all together IMO. It will run (maybe crappy) on the stock tune, but even if you had to get it to a local tuner, you could make it.
