I am so ready to pull the trigger on the tune...
I'm just worried about reliability and longevity. Especially with the CA **** water gas.
I also intend on taking this car to the track (road course) like my other cars, but I'm worried that the tune may give me some problems (I had issues with my tune on the GT-R at the track). I assume with both the Rebellion and Renntech tunes, I can dial it down?

I would not tune if you plan on tracking it... At least not yet.... certainly not with a piggyback.
Once more tuners come in and more testing and refinement is done on tunes I would say they are not "track ready". Give it another year

Our CL/A45 mates in Sydney Australia are running: Rebellion v2; Renntech; Willall; EvoTech and McChip-DKR. We are planning a dyno day soon to measure before and after % increase (not car v car) and we're expecting similar numbers. we've also strapped on our GPS vbox and have been to the drag strip and can say that we're all running similar 0-100kph (0-62mile) and 1/4 mile times.
I've personally run 2 tracks days so far and had no problems, as have the Willall units (which have been extensively track tested).
whats certain is the power increase (no matter the brand). once you drive with a stage 1 ECU, you wont go back to stock. As to which one you want, well that's up to you - price vs supplier reputation vs local support vs claimed power, etc. I concur that the gearbox is now an issue and the extra power highlights this a lot (big delays in gear shifts and short shifting 1st and 2nd) - but it wont spoil the BIG GRIN you get when you plant your foot!

on the vbox anywhere from 4.1 (with RS) to 4.6 (soft start) for 0-100kph
at the drag strip, 12.2 to 13's (yes, slow day that was) for the 1/4 mile
of more interest are the track times. An A45 with Stage 1 "Tekno" tune ran a 1.037 at a Sydney Racetrack recently in the MOTOR magazine test (will be published in July). the track record is in a Radical SR8, on slicks driven by a local racing driver at 0.53sec (porsche GT3's are doing 0.58/9's). 10 secs off the track record is not bad!

As for the tunes - 3 cars on track. 1 Rebellion. 1 CPC (McChip) and 1 stock. Obviously the tuned cars better lap times but the big difference was coming out of the tight, 2nd gear corners - more power, stronger mid revs. So - Piggyback ECU tunes at the track? Absolutely (just be sure the temps on the "AMG" menu are ok (not blue)).
