Correct, but also varies depending on who you talk to. Jannetty Racing and Vengeance Racing both told me there's no benefit to TCM tuning an A10 until a cam is installed in order to raise shift points. The other scenario would be if your car makes enough power where torque management becomes an issue but its highly unlikely you'll reach that point until you have a cam. I have heard that the stock A8 programming isn't as good as the stock A10 though.

I don’t think its the same for me, i have a 2650 maggie on with a 85mm upper and meth for now, but i have more upgrades on the way, i have a vvt1 tsp cam with a 9.17 ati lower pulley and dsx low side fuel pump, i think i will have to go for higher rpm so i dont under drive it.

The transmission question aside, are you pushing 800 hp without meth or fuel? That looks like a low number for a maggie cammed, modified heads.

I'm no Expert - but my A10 is ALWAYS in the right gear - and when it comes to tuning the A10 - I trust GM R&D over a independent shop

Did either shop say what that power point is… about?

Just as aftermarket ECM tuning can produce better performance, the same can be said for TCM tuning

Have you had your A10 tuned? if so what differenced have you noticed or what benefits?

Not really but it's not 700whp.

The tire height difference of more then 1" front to back will cause stabillitrak to freak out.

Yes there are gains to be had on Trans tuning on both the A8 and A10 even on a basically stock car.

Some will say it's not worth the cost to tune the A10 until you have more extensive mods and there might be some truth that since the cost for licensing and tuning the A10 stuff is expensive. But either way there are gains from it.

For example, the stock A10 tune will not allow the throttle to fully open until like 5k rpm in first gear which limits the 60ft capabilities. The info is out there just have to do a little research for yourself and you will see.

That might be a good thing if you're making more power than traction.

You guys beat me to posting this.

I've been a believer, and this is a fair representation, it seems to me. I'm not sure why other calibrators say it isn't, but as far as I can tell, it's not a waste, IMO.

It seems like you can clearly see the difference in shifting between the non-PCM-tune-runs and the Pray-runs. The camera seems to shake pretty good on the later shifts.

Gaining speed without adding any power seems like a win win to me. I think it’s $200 to get unlocked and four credits via HPTuners. My CAI was $750. I’m sure a TCM tune will make a bigger difference than my CAI and ported TB combined made untuned.
