#1gs300

no i dint i did it the following day.

If in fact what you describe is the case = About 200 miles should do it. Keep us up to SPEED on this. PLEASE thanks i'll try @ 200 mile then let him check it again.

:( Hey guy's quick question i just installed my borla exhaust on my car, and i love it i resetted my ecu by disconnecting the negative wire. I took my car to my friends shop, and asked him to put it on the machine just to see if everything was cool, and of course every thing was fine, but he did tell me that the catalyst sensor didn't reset. he said its nothing to worry about they will clear on its own he didnt remember how long i had to drive the car for it to reset. he said it will clear, the question is do u guy's have any knowledge of this after resetting the ecu. The only reason i took it to him to check it out is because since i had the car ive been noticing lower miles to the gal. I recently bought the srt intake with piggy back ecu. I wanted to make sure nothing came up before i installed the intake. he just said by me resetting the ecu if i was to go & get my car annual inspection it would fail. I'm just curious how many miles do i have to drive for the catalyst sensor to clear. By the way i have a 98 gs300.

go on ebay and in the search column type in lexus gs300 and there is one that is $175.00. I bought 1 for my car in know u have a gs300 but the grill will fit ur car. Also i bought H.I.D's 8000k & they are bright !Removed! sh*^. if u need the link to that site or the number holla @ me. The hid's was 305 shipped.

98 gs300 in 2002 when i bought my car i took it on 95s and had it on the governor and yes it actually works once it goes on the governor it knocks 10mph off then when u get it on again it just does the same. So to answer the question it was around 144,146mph.
