Order a tune from Bamachips my baseline with hotrods from him was 336whp running rich... My dyno tuner was impressed with his work.. For a mere 50bucks it was worth it....
You should not have to send your tuner out they can send you tune files via email...
You can download the xcal3 tune program off of the xcal site. I needed to download it for my xcal2 when I got my 4.10 tune. Piece of cake...and they even explain how to do everything step by step.
thanks man! im getting a tune emailed to me for my manual transmission so i dont have to buy a new ecm and i really have to figure out how i can download it
