After I got the Flashpaq installed Friday, I decided that I want to go out today and tweak the settings I made just to see if there is any gain or loss. I started with 87 octane, 6200rpm, 120 mph. Question is, when I go and plug the computer back in, do I have to go through all the read stuff again like the first time, or can I go straight to the change settings and then program it?

 

good question,I am thinking about buying the same programer,please tell us how you like it and if it is worth the money!!

 

If you're just adjusting the rev limit just change it and reprogramme. I believe you can do the same for the octane tune but the general feeling is that it is safer to go back to stock first before changing the performance level. You'll find that there is a big difference between each truck as to how the SC effects it. Some have idle trouble, stuttering shifts, no shift at WOT, all kinds of weird problems, especially in the 91 tune. Often just changing the rev limit a bit will make a difference. It's a great tool but has it's problems and individual quirks. SC are supposed to be bringing out some online 'fixes' at the end of the month but they said that for the last few months!!
Good luck, take your time, follow the on screen prompts CAREFULLY and have fun!

 

Read the manual. You'll find what you need there.
