Im looking for a performance chip for my 07 is350 does anyone know ir has a good one and what gains you got?
Ive seen the gf idk if its legit its like 60$ for 30hp and 30ft tq seems too good to be true!

Too good to be true like most of them my friend... There's no real "performance chip" for ISX50s. You can find throttle controllers but all they really do is trick the driver into believing the car is quicker. Absolutely no power gains available from any "chip" that claims to work on our cars.
Sorry pal

From what I know there is no performance chip at all. Our ECU's are untouchable the only gains you get are from intake, headers, mid pipe, and exhaust. There is also the supercharger but I don't think you want to spend that kind of money.

Acccctually, a member did successfully chip their IS (no BS) but it won't work for you unless you have a 220d.

You'll get more gains by removing the spare and vacuuming your car I've actually had a lot of gravel accumulated up on my under panels.

Haha. I'm finally on CL long enough to see 3 - 4 of these threads pop up over the years.

To the OP: No ECU chips exist for USDM IS350/250. Unless of course you decide to go the all-expensive and elusive turbo/supercharger route.
