Spent the last hour or so searching and reading posts about tuning and tuners. Seems like all the posts are about tuning LS1. I have a 98 w3.8 that is my daily driver and will do some time towing my boat during the summer.

Changes I think I need/want:

Adjust speedo for 3.73 gears.
Firmer shift, changed shift points, quicker down shifts.
Improved economy on highway.
Any other adjustments to take advantage of B&M Trans cooler and engine oil cooler and 180 thermostat.

Would I be better off with a mail order tune, or drive it to a sponsors shop or other.

PS, got to get the gears and True-Trac installed before the snow flies or I won't be going anywhere with the open rear in the snow.
