ill see what i can find out. my guys at the shop i go to went to SEMA as a buyer and when he got back called me up and told me he had a surprise for me. told me he just ordered a program where he can tap into my ecu and sqeeze out more power. i asked him how much more power... the vender told him up to 25. so i dunno if its true or not since he's still waiting for the program. we'll see... keep you guys updated once i get more info.

Revised ECU for IS350 from TOM's
Guys, I just googled "IS350 ECU SEMA" and it showed this at the top of the list...
In 2007, the Japanese TOM'S aftermarket tuning firm produced a modified IS 350 with a revised ECU, new air filter, modified exhaust, and additional ...
en.wikipedia.org/wiki/Lexus_IS - 79k - Cached - Similar pages
However, once I clicked on it, it said nothing about TOM's or a revised ECU being @ SEMA....Just the general definition of the 1st-gen & 2nd-gen IS.
If any of you have the time to do some research, this is a good start seeing as it did talk about it being a "Revised ECU from Toms" in the search heading...

I see...
Well, if that's the case, then this guy's shop(IS350Johnny) is getting him a program that will not be applicable for his car, seeing as it's NA.....Unless it has the same effectiveness as buying something like an E-manage for a "near" stock 350, which is slim to no gains from what I hear.

I promise your reduction in mileage has nothing to do with the new intake. Fuel economy naturally drops off when it gets colder, and it looks like you're in a pretty cold area, right? Even down in Texas, my highway mileage has dropped significantly over the past couple months, and I haven't changed a thing. Actually, I just did a 400 mile trip over the weekend, and I didn't get any better mileage than you.
You also need to keep in mind that there is a HUGE difference in economy between 60, 70, and 80 MPH. I would be that you would easily average 30+ MPG with the cruise set at 60 MPH. The difference for me between 60 MPH and 80 MPH is almost 10 MPG.
