Luke Posted October 30, 2005 Report Share Posted October 30, 2005 What kind of milage are you Radix guys getting? I'm getting about 17 MPG right now with a CAI and Bryan's tune. Should I expect to see a drop in milage? Also, I have a 160 deg stat. Does the programer that comes with the kit allow you to adjust for a 160 deg stat. or other mods? The only thing that is stopping me from getting one is possibly the loss of fuel efficency and overall reliablity. I put on about 500 miles a week. Is this SC designed to last for the life of the engine (100K)? Link to comment Share on other sites More sharing options...
Chris2005SS Posted October 30, 2005 Report Share Posted October 30, 2005 I'm at 17.7MPG with Radix, Catback and CAI. I've got about 7,000 miles on the Radix and the reliability is excellent. Most of the time, you never even know it's there. Go for it!!! Link to comment Share on other sites More sharing options...
dcairns Posted October 30, 2005 Report Share Posted October 30, 2005 45K on my Radix. Highway MPG will remain the same. Stop and go driving will go down some, I get 12-13 MPG around town. But that is more about how much fun it is to floor it The Radix really does not reduce your MPGs, it just allows you to get worse MPG if you can't control you foot So the reality is, you will get worse MPG, because you can't stop yourself from using the extra power. Unless you get Bryan to make you a new tune, it will be overwritten by the tune that comes with the Radix. The tune that comes with the Radix is not adjustable in any way. If you can afford it, just go get it. You won't be sorry Link to comment Share on other sites More sharing options...
H2Racer Posted October 30, 2005 Report Share Posted October 30, 2005 The only way mileage will drop is if you keep your foot in it a lot and/or if you live in a area with lots of hills and inclines. Hills get you into boost very easily on some combos. Link to comment Share on other sites More sharing options...
BRUTONMOTORSPORTZ Posted October 31, 2005 Report Share Posted October 31, 2005 16-17 mpg on the highway. 12-13 mpg in the city. 4000 radix miles with no problems. Link to comment Share on other sites More sharing options...

Luke Posted October 31, 2005 Author Report Share Posted October 31, 2005 Dang, I've really got the itch now. I have the money, so I don't know what I'm waiting for. I'll let you know when I take the plunge. Thanks for the input guys. Link to comment Share on other sites More sharing options...
TBSS Posted October 31, 2005 Report Share Posted October 31, 2005 My mileage did not change - well, wait, it actually got better, because the stock Superchips tune that came with the Radix was more efficient than the factory tune from GM. I consistently got 19.5 - 19.7 MPG on the freeway after the Radix install (until I swapped my 3.73's for 4.10's). Not bad for a 5800 lb vehicle. The tune that comes with the Radix is not adjustable in any way.<{POST_SNAPBACK}> Hmm, I don't quite understand this. I have HP Tuners and I have adjusted and modified a few things in the tune that came with the Radix....mostly shift properties and top speed settings, but I have modified it nonetheless.

dcairns Posted October 31, 2005 Report Share Posted October 31, 2005 What I was trying to say, is that the tune that comes with the Radix does not have any adjustments on the hand held tuner that they use as a downloader. Some people get the idea that because it comes on a hand held tuner like device, that it can be adjusted with it. You can certainly use LS1Edit or similar programs to download, modifyand upload the stock Radix tune. Link to comment Share on other sites More sharing options...
TBSS Posted October 31, 2005 Report Share Posted October 31, 2005 Ahh, so you meant the tuner doesn't have any adjustments, but you can change the tune 7 ways 'till Sunday. Gotcha. Link to comment Share on other sites More sharing options...
kbracing96 Posted October 31, 2005 Report Share Posted October 31, 2005 Just do it man!! You will love boost! Let me know if I can help! Link to comment Share on other sites More sharing options...
SSLink Posted October 31, 2005 Report Share Posted October 31, 2005 I'm close to a couple of the guys above. I get about 13 city and 17 highway. City probably would be better but I have a heavier foot now that Zippy tuned the truck to run well. I guess I can blame him... Link to comment Share on other sites More sharing options...
