Rebellion Automotive have a piggy back system (ituning). I'm considering it but waiting for someone else to be the guiney pig!!

to me it seems like the piggyback would be safe to try because it is a reversible modification.
now can the file on the piggyback be altered to cater to the specific mods on the car.

I think this is a bit of false logic. If the piggyback unit has an unsuitable tune (i.e. too much boost, too much advance, not enough fuel etc.) and you blow up the motor, the fact that it is removable doesn't change that your engine is toast.

I'm very surprised on this forum that the vendors of tunes do not provide very much data. At a minimum, they should be include a before and after comparative dyno graph, and for the M157, show comparative boost and AFR. Only with this data can the consumer meaningfully speculate on the effectiveness and safeness of a tune. I'm not sure why vendors here are not willing to provide this info as it is readily disclosed on other forums for different platforms.

when i said safe i meant in terms of drilling the ECU vs the piggback

I understand your point. An aggressive map will cause damage to the motor eventually if it is loaded via a bench flash or piggy back.

Where are all the Kleemann M157 tunes? Here it is: the Kleemann Tuned CLS63 (ECU Tune, Turbo Pipes and Catless pipes by Kleemann, BMC Air Filters, Brisk Racing Spark Plugs and Resonator delete) up to 770-800HP. I was using 100 Octane Fuel.

That cls sounded awesome ! Was a bit dangerous but I enjoyed watching it. Seems like the kleemann tune is working

Indeed, that sound is amazing. We represent Kleemann in Republic of Georgia. This is the first car we tuned so far. On Wednesday we will post Dyno results.
The next step is to modify turbos. Let's see what we get.
