I agree with BOTH previous posts...
Unless you have a very crafty dealer, they wont be able to "see" aftermarket injectors. If they drive it and feel a noticable increase in power, they may suspect "something strange is afoot". If they see any kind of a boost fooler, they might void warranty just on that alone. If no fooler is present, they may find an over boost fault if the waste gate has been disabled. Now you do the math.
Bottom line-
If you play, you might pay. Going to court for fraud is something I dont want to face. Do you?
Repeat after me... I am my own warranty station.
Not directed at anyone, just a heads up.
