I'm on a quest to increase the hp and mpg at the same time. I purchased a module (RVP) from ebay that claims to be able to increase hp by +50 and mpg by + 10 - 15 by connecting this device to the Intake Air Temperature Sensor or the Coolant Temperature Sensor. Where can are these be located on the GS 430 and is it a good idea to add this to my lexus?

I filled up last week at 145,458 and ran it completely dry 146,020, which is 562 and I put 16.176 in the tank. So, it currently is running around 35 mpg (alot of highway miles) with new oil change, tire rotations, fuel sys cleaner, and K&N air filter. Trying to make more hybrid and keep power...lol...gas is rough at $3.80/gallon.

Hey all. Brand new to the site so I hope I'm doing this right. GSNOLES the GS 430 is definitely your best bet with the options you mention. My GS 430 has 147k and hasn't had any problems at all. Great ride and serious power.

Hey all. Im looking for some seasoned GS owners' insight...after about 4 months of research Ive decided im going to buy a GS...Only problem is deciding on a 2000 that looks good one owner no wrecks far as I can tell...with almost 79k mi. for about 14k.. or spending the ten grand additional on a 430 around 03 or 04. I know opinions vary on the two but Im looking for major downsides if any and just some 2 cents from informed owners. SO if you guys can warn me of any MAJOR drawbacks of going older its very much appreciated. Also is 14k a fair price for a 00 with nav, one owner with no known paintwork or wrecks? Or am I overpaying??? I plan on doing the 90k maint, but not till then of course. Its from a non-lex dealer...I also was considering one from a lex dealer that is about the same milage but its a base car, no nav..similar on price one owner, no wrecks...the 430's seem to run around 25k which is a lot for me for a used car with 50k in mi's. thanks in advance fellas.
