#8 of 11 Diablo Predator by dsteber Apr 19, 2008 (4:36 am)
I have searched and searched, but I have yet to find any custom tunes for it. So, it looks like I will just use the one that comes with it. You see, with the Mustang, the tune changes for any mods you might have. So, I don't know if it will affect it when I add the cold air intake or not. We'll see!! I know what you mean about the lag. sucks. But, it sure is alot better than my Infiniti QX56!!

Replying to: dsteber (Apr 19, 2008 4:36 am) I put a Volant CAI on my 08 Denali and it seemed to make a significant difference in performance. Fuel mileage seems to be somewhat better but it could be my imagination. It's getting 15+ with both HWY and City driving and I don't really drive like a grandma. I plan to have the exhaust done and possibly the Diablo programmer. Is the U7194 Predator the correct programmer for my Denali? Stock HP on the Escalade is 403. Is it in fact the exact engine the Denali has? The Cadillac site makes reference to the VVT on the 6.2 in the Escalade.

Replying to: rsktkr (Jul 08, 2008 9:06 pm) Yes, the U7164 is the one that I have. I will have to look into the Volant CAI. Did you have any check engine light come on after the install? It would be nice to get a tune on my diablo that had the CAI factored in. I just do not know where to get one. Replies to this message: rsktkr (Jul 09, 2008 8:02 am)

Replying to: dsteber (Jul 08, 2008 11:29 pm) I got my Volant CAI at 4 Wheel Parts. The part/model number is 15253. I didn't have any check engine lights come on. I went in planning on getting the AFE intake but the Volant was the only one they knew for sure would not cause any check engine lights. It's a clean look and pretty simple to install. I paid $313.91 for it out the door but they were having a 20% off employee discount. I just got it 10 days ago. Here are some pics of it installed.   Does the Diablo make a significant difference in performance? How negative is the impact on MPG?
