What kinda parameters are typical to change on a 5.3? Just wondering we have a suburban but ive never plugged into it.
Is there much to be had from these? Its a slug.

biggest thing your gunna need is a air/fuel ratio gauge, then from what ive been reading its fairly easy to do if you have been in a gas tune before.
I would give a call to Wester's. We've tuned a few gassers with some very good results using his software. Power you can actually feel!
pcmforless.com is also an option... I've had good results with them in the past with my gassers.
I had a guy off DP that was gonna send me a tune for our 5.3 burban, guess he forgot. But I say supercharge it too if your looking for power, I don't think you'll be very happy with the out come of a tune
Im pretty sure I have tune for a 5.3 thats supposed to be stout. Its not for the 07 but you can look it over if you want. Ive never used it for anything but your more than welcome to have it....PM me your email and Ill send it over.
Best thing for those motors is a cam. Throw in a Texas Speed cam and it can still be streetable. Also you can tune in a little more aggression with using the E85 gas but mileage will suffer a tad.

Just got ur PM. Ill try to find it and send it your way. Just make sure you look it over. Im not responsible if you blow your shit up as Ive never used it! 
I have been plugging in and "saving" stock tunes on several gassers but I haven't had anything to play with to try and tune it. I have one from an 03 6.0 escalade that has some major balls off the line but being all wheel drive it shuts down about 80 mph I drove it and thought it would be a perfect start to my 6.0 firebird project. I also have one for a supercharged 5.3
