predator
The predator does say when i click on trouble codes that the P0602 P1211 P1690 P0605 are normal for tuned cars. I am new to the predator so I wasn't sure. I got it just for the stock tune and to calibrate my speedo for my 4.10 gears.
ive had mine for awhile but just started to use it... i got mine on ebay for under 100 bucks...my car only has exhaust upgrades and i had it dynoed...we got a 20hp jump with just the performance tune...
i think i remember it also says that while installing a tune ,,not to have anything on and door shut or a problem will/could happen and you will have to redo it,,,
i amit i sometimes over use mine to clear code 455/457 instead or fixing it,,
po1000 has popped up on me also,,
im not the pro here but i think po1000 will clear itself after drivecylce is complete,,it normally wont lite after reseting of pcm,,but ive come across the cel coming on and no code being present,,now i find if i wait till after a full cooldown and cold restart that cel could go out or codes will appear
