• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Fuel mileage and bad shifting, wrong shift points etc can be related to needing a tune up.

When was the last plug and wire change?
Last time you cleaned the TB/MAF?

billboost- i have noticed my shift points moved for overdrive. usually it shifts around 45,46ish... now it likes to shift around 48, 49 most of the time around 50 though.

i put some of the cheaper NGKs in there. should i change them out for better plugs?
