Conquering the (NNBS) P0449 Code
I have to thank 5.3SLT for this thread. My Yukon Denali 2008 (6.2L AWD) was having a rough idle, and was hard to start after fueling it. It gave me a message saying “Tighten Fuel Cap” and after trying to remote start it gave me a P0496 code. Until I did all the recommended changes, I wasn’t...- Javi

CORSA muffler only?
I wanted a more aggressive note in my Denali, also the idea of more horsepower was in the agenda. After looking around several catbacks, I discovered that they were narrower than the stock piping. My Denali is 3.5” while the catbacks where 3”. There was no logic going to a more restrictive...- Javi

2009 yukon denali quarter mile time
Look, I don’t like it when someone tries to call me a liar, as I’m sure you certainly don’t either. At the same time, I don’t like to insult nor be insulted. I can agree that people on the net get carried away and for some reason want to live an alter ego, specially on forums. I can only give my...- Javi

2009 yukon denali quarter mile time
That’s right, I have nothing to prove, don’t sell anything, just giving my honest experience with my SUV to the forum, I just informed another fellow member my ¼ mile times with my mods (which is what the thread is about) and the list of trucks I have had fun with (to give examples), and for...- Javi

2009 yukon denali quarter mile time
I never said I have taken a Cayenne Turbo on a race, I said a GTS (I haven’t raced a Turbo…yet!). I really don't care if you believe me or not. When I mentioned ML, I meant the ML63 sorry for the confusion. Denali vs SRT8: http://www.youtube.com/watch?v=stLNaV45Ml0&feature=related Here is a...- Javi

2009 yukon denali quarter mile time
If your source for timing is a magazine, then we are wasting time arguing for nothing. I’m not trying to sell anything here, nor need the attention. I’ve seen Cayenne turbos at the track making low 14’s all night long, but no 13’s. A Cayenne GTS, is no challenge, at least for my Denali. But a...- Javi

Top Speed
I'm not encouraging to do the same, but I have clocked in my Denali 139mph with GPS (the only way to know). With better conditions I would bet that it could do better (there was not enough road). It was late at night and had my Beltronics STI Radar Detector on (bad ass radar BTW). The truck has...- Javi

All runs where made in 3rd, 4th is too long. ---------- Post added at 05:42 PM ---------- Previous post was at 05:38 PM ---------- The thing is that our trucks (at least the 6.2L) run extremely rich (my truck was running 9.8 mixture OEM stock) so when doing the intake mod much more air gets...- Javi
