I haven't figured out how to read rail pressure on my early (Oct 02) 03. Are you sure I can and how do I do it? Craig

Please give me a pt.# and the supplier for the correct usb/serial cable for my desktop Dell computer windows 7. I've called Radio Shack and Bestbuy and they barely know what I'm talking about. I tried a search and came up with many usb/serial cable types and I want to get it right the first time ...

I have the 7130/puck stack but RARELY use the puck because the predator will do so much on it's own. I like the stacker extreme tune (no puck) for the better driveability than the hotter tunes. It runs VERY respectable! Then, if a rare moment comes and I want more, I turn on the puck 50 and get ...

I've been having problems since I had to replace my APPS on my 03 with U7130. The new APPS cured all the previous problems with codes so I tried to load a tune and it said it didn't go in. The tool said to disconnect the batteries and try again. I tried again and it still wouldn't go in. Then it ...

There's no 100hp perf/puck stack. I wish there was one, too. I've tried the puck with the 100hp and I didn't like the engine sounds at all. Turn the puck off with the 100hp tune. I really like the way the extreme stacker tune runs, with the puck off, but the throttle is touchy. Craig

Install the stock tune before DLing a crom file (revision) but you don't have to install the stock tune before DLing a custom tune file. 8r29, 9r03 etc are revisions and you only use the appropriate custom tunes for your rev. - like pre r28 or post r28 tunes. The first time is the hardest and then ...

My first mod was the turbo - the stock turbo and muffler are both TERRIBLE! Craig

I don't know that much about them but I don't trust the inertia dynos at all. I've seen numbers from them that were obviously and totally way off. The first dyno mine was on was a big truck dyno. It started with the throttle on the floor and the dyno pulled it down and showed TRUE brake hp - not ...

Just wondering... what truck is it on - is it the right application? I think I read in my manual that there's something that has to be done before running it on another truck but can't remember the details. You will like one that works properly! Craig

Mike sent 9t04a to me and that one worked but I still had to load a regular Pred tune first then the custom tune on top of it. Try a canned tune first. There's a lot more about that in the "7130 updated" thread.
1. Load a canned tune.
2. DL the custom tune from your puter.
3. Flash the custom tune ...

I just want to compare notes with someone! I've been checking the 6th gear 60-80mph times with all the custom stack and nonstack tunes. I picked 60-80 cuz that's the rpm range where I want really good power and city driveability tells me if I like the bottom end power of a tune - I want smooth ...

Mine works fine with the 9t04a that Mike sent me but not the one that Johan sent, earlier. I don't know what the difference is. I deleted Johans file already but I think they were both 9t04a, the same size files and exactly the same file name. Craig

Not always. I lost a stack tune when I went from r22 to r29 but got them back when I went to 9r03. After I went to 9r03 I added a Puck but couldn't use the stack tunes with 9r03 - technical problems. Now they have 9t04a and it works with the stack tunes. Once you DL the latest rev you can't go back ...

Yippeee, it works!Perf Stack is disappointing (way less beans than the regular perf tune) but Ext. RKL Puff Stack is the fastest one, so far, and lowend/driveability seems acceptable. I need to drive it in town to tell for sure. I was surprised at the lack of smoke (I like that) - only an initial ...

I and several others get a little better mpg with the regular Extreme tune but the throttle is way touchy and hard to control smoke in city traffic. I'm trying the custom tunes now. Craig
