I've seen discussion on the LNF upgrade (which I just got and LOVE!) and I've seen discussion on the Hahn Autotune which seems to work very well too, but I don't think I've seen any discussion on whether the Autotune will do anything for an SS that has had the LNF upgrade. Anyone? I guess what I'm wondering is if whether the LNF and Autotune do similar things where the LNF is unchangeable but the Autotune is and that installing them both will not gain you much more performance. Granted, the car is scary fast now, but to me there is no limit to how scary or how fast you can make vehicles if it's possible and affordable. If I can, I usually will .

INstalling both wont do anything for you. The neat thing with the BSR tune is that you can put it back to stock if you please but the stage kit keeps your warranty

also hahn tune is a 1000...........

You might be able to build on top of the LNF upgrade, but that would depend on if the stage kit left anything to work with.

Or you forgot H/P tuners. But from what I see when I hook up the H/P Tuners the GM upgrade took everything to its limits except for 3* of timing. Wait til H/P tuners comes out with the next update... INSERT SINISTER LAUGH HERE(MMMMMUUUUUAAAAAHHHHHHHH) then we'll see what the LNF is made of...ask me how I know

Andy at ADM got 30 more hp out of his car through further tuning on the upgrade kit...

Furthermore, the stage tune has yet to produce numbers equal to those we've seen from aftermarket tunes.

Factory stage kit is about warranty and safety margins. Any tune that pushes the boost beyond the original MAP sensors' ability to read it is playing with fire. Tweaking the stage kit tune makes more sense, but bear in mind the E69 can rat you out to GM. If busted, kiss your 5 year powertrain warranty goodbye.

well IMO from what i noticed,all tunes as of right now are all the same. period. no one is seeing more boost or more hp than the other. i'm still skeptical of the gm stage tune combined with the h/p tuners. so far only one person-a tuner- has achieved this?? i need more proof from other owners. like i said before,we all got our cars for a purpose. it's good to have variety so we all can compare. however,at the end of the day,they are all the same,even when it comes to price. yes the hahn is a $1000,but by the time you get an hp tuner,dyno time,etc... you have come close or equal to the hahn. the gm tune is half of that,but all i've read about this tune is that the goobers(not all of them)at the stealership don't have a clue and most end up bring the car back because something wasn't hooked up right. then in some cases,they are charging more than the $75-$100 for labor. to each his own though. right now,till hahn,h/p tuners,trifecta,and whoever else out there "unlock" new settings,we are all sitting in the same boat. the only other option now is a bigger turbo or nitrous.
