I have an appointment at the end of the month with SpeecInc for a tune on my new upgrades over the winter. I know, my guess is as good as yours, but from those of you who may have similar set ups, what numbers have you put down? Also, possible track times if anyone has them.

Car is a 98 M6
Full list of mods:
TSP 233/239 cam
.650 dual valve springs
Hardened 7.400" pushrods
Ported ls6 oil pump
ls2 timing chain
ls7 lifters
Monster stage 3 clutch w/new slave
Borla cat-back
pacesetter LT-headers
pacesetter y-pipe
ls6 intake manifold

Also, any other low cost mods what are recommended before I get the tune?

my guess is 385-395whp. .. 98's have the 806 casting heads and totally suck .. regarless you should see a good power increase and it has potential for more if you decide to upgrade the heads

Those arnt too bad of numbers. I'd love to see 400 on the dot but like you said these junk heads will be holding me back like crazy.
