2000 Z28 M6, bolt-ons
Basically would like to know how fast I can go with stock manifolds, and the stock LS1 intake.
Mods currently: SLP lid, SLP CAI duct, walbro 255.
Mods upcoming: TB coolant bypass, maybe 180 stat, true duals with X-pipe over axle, high flow cats. HP tuner
Mods considering: bigger injectors, MAYBE (doubtful) LS6 intake, MAYBE 3.73s.
So what's the best I can hope for with just lid, duct, exhaust and tune?

By pass is fine, helps keep heat out of the TB. Leave the stock thermo in there, do not do bigger injectors unless your moving up to heads and cam, or if they are there to support a Dry Nitrous Kit. A LS6 intake is a GREAT mod and very inexpensive in consideration.
Gears will be fun but for your tranmission just go 4.10's its a NON issue and the car will perform better. At best get a whole 2002+ LS6 intake as it has the better injectors by a few pounds but I would not spring for aftermarkets.
