Hey guys,

tuning a mild cammed LS1 seems to b driving nice, good afr's good trims and not to bad driveability.

Having one issue with car seeming to want to drive on at about 1500rpm, the return to idle is extreemly slow.

The hole in the standard T/Body is 4mm.

Where when wat how and y?????

I will post tune wen I get back to the workshop
