Unhappy 87 octane tune for diablo predator

Hi guys:

Can you guys give me some advice. I live in a small town that only has 87 octane gas available( i know small town). I have been reading a lot about the Diablo Predator, and i am debating getting one for myself. Some people say the predator is not worth it if you can't use 91 octane, and it can cause engine troubles. The main reason i want it is modest hp gain and the main reason fuel savings, can everyone who uses 87 please help me out. I don't want to spend all that money without any benefits or the possibility hurting my truck.

Well I am pretty sure that you have a chance of hurting the truck no matter what tune you are using. I am not sure why the 87 tune would cause anymore damage than the 91 or 93. On all of the settings you are pushing the truck past factory limits. I am running the 87 right now (mainly to disable the stupid MDS), but I can definitely tell a difference. Is it a 300$ difference? Probably not but it is worth it to me. It livens the truck up a bit and gives some more pep. Good luck with your choice.

EDIT: I just saw where you were talking about fuel mileage gains. I am not sure if its because of the weather beginning to warm up or the predator but I have gained about 1 MPG since I put it on my truck. Everyone will say something different, but this is what happened in my case.

I have the 87 performance tune in mine, I tried the 91 tune and it was a slug, the 87 performance tune run's real well but run's the best on 89. I had the 93 tune in it for about a year but to tell you the truth this 87 performance tune runs just as good as the 93 tune did and I get the same mpg so I'm sticking with this 87 tune.
