Replying to: markisliev (Aug 19, 2007 7:07 am) I'm from Dallas....but the rig is in Crockett Texas. How about you? Yeah....the white looked the best to me. My plans are Escalade rearviews (the chrome and white to replace the black and white), touchscreen nav. (dealer installed factory unit. It's actually 650 dollars cheaper dealer installed than factory installed for the same unit.), 22 inch Giovanna rims (custom Summit white face, chrome lips), h.i.d. headlight kit, Borla dual 3 1/2 exhaust, chrome 6 inch oval step bars, colormatched white Rhino Liner, shaved and relocated tailgate handle, shaved and removed tailgate edge protector, white GMC emblems front and rear, and finally headrest screens (maybe...headrest screens can be ghetto sometimes). I think I'll have a classy ride in the end. Replies to this message: markisliev (Aug 19, 2007 9:17 am) guysykes (Aug 19, 2007 5:23 pm)

Replying to: guysykes (Aug 19, 2007 8:29 am) Lafayette, Louisiana here...I never been a huge fan of white, but really liked the way it looked on this truck.....I have outlaw intake, PCM tuned with HPTuners, Magnaflow muffler, and 2'' rear drop shackles ...Is Borla comming out with a kit for our ride? That would be sweet... I just bought a Du-Ha for underseat storage... Du-HA Here is a sound clip of the new muffler....I would really like a "clean" catback, this is only a temp solution until they come out with something...

Replying to: markisliev (Aug 19, 2007 9:17 am) Not exactly a "kit". One of my bro's works at a muffler shop. He's thinking custom bent stainless, and a borla muffler kit for a WS6 TA. He isn't sure about fitment yet. I'm going for a really agressive sound. Not so much the "cracking" farmtruck sound. ( You live in Louisiana....you know what I'm talking about there.) How is the programer? Any loss of quality in terms of smoothness shift points ect. I'm interested, but I don't want to void my warranty, and I don't want my truck to ride like a S-10 with a 502 under the hood. Haha. How much $? How many gains? How much difference in power? Does it eliminate the 100 mph governor? Where do you get it? Is it safe for the truck? Haha....1000 questions......
#89 of 128 Tuning by markisliev Aug 19, 2007 (5:54 pm)
Think of Hp Tuners as an advanced handheld programmer, you do everything from a laptop. More gains are possible with this over say hypertech "hypercrap"..lol! You can save your factory tune and load it back to stock if you go in for warranty work. Look at HPTuners.com 500$ The gains are very noticable so far. I have no delay when I hit the gas. I would not suggest this for idiot's like skytop1, he may kill himself. I'm still tweaking things "slow and safe". The biggest gains so far have been from advancing the timing and changing the shift points. The 2wd's shift at 5,500 from the factory, our motor makes peak HP after 5,700. These trucks run pig rich from the factory, more power can be had leaning out the air to fuel ratio to 13:1. You can also tweak the speedo, change tire size and get rid of Tq management in the shifts.....If I turn off Tq management in the upshifts my truck will go sideways in the 1-2 upshift...bout 34mph..lol. My tires really don't like me a whole lot! You can do what you want with the tranny...wild, mild, stock or anywhere in between....I'm not sure what the gains are right now, never made it to the dyno yet. I'm wating on a wideband o2 sensor once I get my AFR dialed in I will load the stock tune back on and do a dyno comparision...The only thing is that you must know someone who tunes, pay somone who tunes, or you need to learn the software on your own.... you can break stuff if you don't know/understand what you are doing...that's the only disadvantage to a handheld programmer which will babysit the average joe through the setup, but has less capability....Is it safe???Well more power = more stress on the drivetrain, depends on how you drive your rig..just gotta know what you are doing. GM really detune these motors to make sure the drivetrain can support a 100,000 mile warranty....

Replying to: guysykes (Aug 19, 2007 6:50 am) Dude - What happened to your front bumper? It's tilting down, the gap wider front centre than on the side. See post 63 of markisliev's to see what I'm talking about. The gap is consistent all across and the ends at the wheel-well line up. Also, you mentioned HID headlamps. Are these available? If so, where? k- Replies to this message: guysykes (Aug 20, 2007 12:27 am)

Replying to: kobiashi (Aug 19, 2007 9:18 pm) Yeah.....those pics were taken the day I got my Nali. The dealer told me it was a couple of loose bolts on the front bumper.? They fixed it the following week when I had time to come in. It took about 15 minutes, so no biggie. H.I.D. I'm not sure if there's a kit yet......but I know for a fact that there will be one. Mark......thanks for the info.....I'm not sure if I'm gonna go that far with the engine mods though.....I'm planning on getting a Z06 in a year or so.......hopefully that will cure my HP cravings.
