    Hello, I’m currently in the process of boosting a 2006 Mazda 3 with the 2.3L. I was wanting to know if anyone has done this before and any tips & tricks. I heard you can only run on 8psi on stock internals but I’m currently running on 10 pounds. Will this harm anything in the motor?

    I'm curious as to what tires and psi everyone is running. I recently got a set of new tires and am starting to play around with tire pressure. With my setup right now I'm facing some mid corner exit understeer. To combat understeer, should the rear tire pressure be over or under inflated? My...

    I was going through the manual the other day and I glanced over what it seemed to recommend winter tires to be filled +4.3psi over the recommended 36 psi inflation for all seasons/summer radials The science behind it is that the air is less dense on colder weather thus requiring more air. :grin2:

    I'm curious on the 2.5 if anyone knows what psi it runs at. Preferably I'd like to know under load at the higher rpm range. For example, WOT @ 5k = psi?

    How many psi do you lose a month? My '15 sGT 6MT recommends 36 psi cold. At the end of the month, my tires end up at 33 psi cold! :nerd: I'm assuming due to the rubber valve stems and plastic valve stem covers. Other vehicles that I have with a metal valve stem and metal valve stem cover seem...

    I just recently bought a 2016 Mazda isport with the 16 inch wheels. Just wondering what do you guys keep the psi at for the best mpg? Thanks

    I'm just curious, my previous car was a 2009 pontiac vibe gt hatchback and uses the same size rims and tires as on my sGT. If I remember correctly that car uses 32psi as noted on the door and the sGT uses 36psi. The car's pretty close in size and weight so would I be okay to run the mz3 at...

    what is the recommend psi settings to get the most out of the tires, handling wise? i have federal super street 959's and was told that they run a size up. i have 205 40 17 in the front and 215 40 17 in the rear...(215 40 17 front and 225 40 17 rear if the size up is accurate) these tires came...

    We've had a pretty warm winter in NC, but we've had a few cold snaps where the temperatures drop from 60-70 to 30-40. Every time (three so far) one of those cold snaps happens, my MZ3 screams about low tire pressure. I've got the MZ3 sGT, so my tires are 17". I've checked all the tires twice...
