1.wouldnt do the Lightweight optoin/aluminum Flywheel in a heavy truck. i asked "pete" at Spec the same thing and he recomended not to...hence i went with the spec normal flywheel.

2. only opinion....i would go with a ~3" tach to about 7-8,000 rpm. and it could be put in the custom dash easier, the smaller it is. i hate "monster" tachs.

3. Electric throttle control is only on the vette's LS1 in case you didnt know. dont feel like you have to get a vette ls1...looks like you gotta lot of $$ invested in gauges, lol.

4. diagnostics = ALDL
