need help with tunning...(timming) alright guys im going to order the tuner cats program..
the reason why about a year and half ago i got a mail order tune from pcm4less and the issue was we didnt kno the compression of my 355 from previous owner.
pcm4less said it should be good but im getting ready to run 100 shot but wana make sure that the car is dailed in right.
is there a way i can get the timming tables loaded to here for u guys to view them and tell me if their good or not??
i got a lt1 scanmaster could that be any help also

I would run something like the Mallory 685 so you only pull timing when on the jug and that way also have a spark based rev limiter and window switch.
If you are happy with the current tune leave that alone and just use the aftermarket box for retard.

I have little faith in Herter after the problems I had with him on a mild setup and problems I have helped others overcome from him.
Notice I said.........
IMO tuning tweaks for nitrous should be done only when on the jug, use the fuel jets and if standalone fueling fuel pressure to tune the fuel and an aftermarket ignition box to handle spark retard rather than hurting NA performance all the time for those occassions you will spray.
If you had a stock shortblock I would encourage you to consider more than a 100shot too BUT on a "built" shortblock observation says always assume they are weaker than stock **** unless there is strong evidence to the contrary and if the previous owner didn't give you a lot of details like compression IMO it is safer to assume you have **** than to think it is any better than stock. I know that sounds harsh, but spend some time around here and you will see just how many "built" engines are junk and how many machineshops are completely incompetent and ruin the machining even if the parts used are any good.
