H&S tuners was popular for awhile also. Especially for 6.7 and EGT deletes. Then EPA got hold of them...not sure what their status is now or how good their products are.
Have you looked into EFI Live. What a lot of us are running now. It is a download program, but still has shift on the fly capabilities. I have 5 different tunes I can run, change tunes by turning a 5 position knob.
Ive been meaning to look into the 5 pos switch deal. I really need to detune my truck even more for city driving but have not gotten around to it yet. Anything I need to know? Any articles I can look at to get up to speed ?
Noplugs...
As far as I know there is nothing special about using the 5 pos switch. I have had it several years now, with CSP tunes from two different tuners and everything still working ok.
Not sure about any articles. I can give you the email of the last tuner I used. He should be able to answer all your questions about CSP/5 pos switch use.
Since my truck is basically stock, the 5 tunes I have are: stock, 12V (single injection, 75hp), street/towing (40-50hp), Hot (75hp), Race (100hp). I have found over time though, that I only use 2 of the tunes; 12V and street/towing.
The 12V tune is noisy (sounds like an old 12V), but EGT's are around 100* lower and see 1-2 mpg gain. I use this tune 90% of the time, especially when towing.
