2. The LNF tune is a “ghost tune” but the LLT tune is not. As such, we generally recommend that people purchasing our LLT tune also purchase the programming cable so they can revert the car to stock programming at any time (using a Windows laptop computer) they need to visit the dealer. The dealer has no way to check the reflash history, only whether the current tune loaded in the ECM is stock, or not.

3. Yes (however see below for more on this)

4. We saw 23HP and 17TQ gain on the very first LLT we tuned. We were doing the happy dance when we got those numbers initially, but some other people ordered the tune and went to the dyno and saw lower gains. We figured out the reason we got such a large gain on the first car was due to the intake system completely screwing up the fuel ratio at full throttle (it was WAY too lean). What kind of gains can you expect? It depends on how much work the tune needs. I can’t promise you any particular numbers, but I can promise you by the time we are done tuning your car will reach 100% of its potential, and this will be proven by the datalogs we get during the tuning process.


Elaborating on the topic of the CEL and engine codes Vince informed me that reverting to stock settings when you take it back to the dealer means that your dealer is going to see the CEL and engine codes caused by your aftermarket products like headers, intakes, etc. So really it comes down to what is going to get you in more trouble with your dealer warranty wise.

Good stuff thanks !
