What's up I got a big 454 in my 95 with a 4l80 and 4:10s needs bigger tires so I'll be doing a vss mod, I'd like to change some things like tps settings if I can cause it runs about 10:1 when it shifts down. other than that it really does run good a 4k rpm. This is the first forum I've been on so I'm glad to be here
About the only real useful piece of information on this site. Although I do find it easier to use the dual DIP switches to mod your VSSB. It is helpful if you ever change tire sizes or axle ratio to be able to quickly change the VSSB settings.

Yes it does run rich if its in passing gear. I have been getting the tools together to use the computer programs until I get the diagnostic link. Today I downloaded WinALDL on my laptop. Is WinALDL a program that's going to let me change the parameter's on the fly like it should, it doesn't look like anything Ive used before, DDL, INSITE?
