Looking at purchasing my first radar detector, I found a r4 that is factory certified renewed or a new r4w. I have done a little research and have come to the conclusion the only difference is convenience with updating. Any info or maybe even ideas on other detectors would be appreciated. ( I was looking at r3s but the r4 seems better )
This happened about 3 cold starts, and then hasn’t anymore cold starts but does a little bit after I drive to work in the morning and then start it again after about 2 hours.
My turbos seals or bearings may be going out, only smokes when the car has been running prior and not on an over night cold start ( the last couple nights atleast ). Wondering what would be a good upgrade that is not break the bank. These were 1750 but on sale for 1000. Might be a bad product but just wanted some other opinions.
Forgot to add I do have a gearhead a/o tune w 3 bar map sensor, if that matters.
This might be a dumb question but am honestly a little confused atm. How do I fill this out for them to send me my tune? First time obv lol
