Another unicorn? We've had lots of them troll through the IS-F forum. As they say in Texas, big hat, no cattle.

I actually emailed the guy. He says he is willing to let one go cheaper and in return, you have to post pic installation and see if it made any difference. He would like dyno sheets of it before and after. Anyone interested, let me know. I almost did it but I'm chasing an ISF or RCF and don't want to spend anymore $.

Ever hear of ECUTEK? This company just came out with a NA tune for the FRZ. The FRZ has the 2grfse like the Takoma and us. This company is getting 10-20+ with the tune. My point being, if they can crack the toyota ecu ( same engine code ) why cant they do it with the is350?
On another note on SAFC-2 - the same engine code 2GR-FSE is also in the old MR2's. Again, gains with bolt-on's yield 20+ hp with the SAFC. Im willing to bet with some dyno pulls that the right tuner, gain can me made with the 3g IS.
Lastly, I have emailed SRT - the have a lot of knowledge with the is300. Im wondering if anyone would be willing to experiment there.

Since this engine has DI, E85 would more than likely result in a nice power bump (my last M3 (non-DI) had a nice 15rwhp power bump with simply running a 30% ethanol blend + a flash tune, my last 335i (DI) had a nice 35rwhp bump with an 50% ethanol blend + a flash tuner to take advantage of it). I wish someone would explore the possibilities of changing A/F, ignition timing, and VVT-i overlap settings, maybe it'll give us competitive power to the germans running stock files (lol).

Urdusa.com make a plug and play EMS for the 05-09 Tacoma's that run the 1grfe (same engine family as the 2grfse). It is better than a standalone EMS as it keeps all factory systems working (including immobilizers, etc). It is fully user tuneable and has every safeguard you can think of (and more) for boosting. Gains for the ecu alone are 20-25whp, and up to 60rwhp with intake/headers/exhaust/throttle body. Maybe you guys should start bugging them to make one for the 2gr
