Go get a INTAKE SET , A EXHAUST SET(APEXI HAVE IT IN STOCK NOW) ,GT HAUS CAN MAKE ON FOR YOU. AND RR racing has the tune. PPE has the header. So with I/H/E and tune you are able for 540HP at crank

Is there a dyno graph to show a 73 hp gain from those mods? Seems like a lot, especially for an NA car.

I saw a dyno on there... I think 70 hp is a little optimistic. It would be interesting to see an independently done before and after dyno with a stock car.. Still seems like a lot of money for what you get. Isn't the intake/headers/exhaust combo with Apexi exhaust like $6000 for just parts? Or with GT HAUS exhaust closer to $8,000 for just parts?

The GTHaus website has their GS F exhaust for $4,000 (not sure if they're cheaper elsewhere), the PPE headers were $2,650 from RR Racing for the RC-F, probably safe to assume the GS-F headers are in the same neighborhood, then intake and the tune would be $1,000ish... so rounding down it looks like $7k plus install costs. Exhaust isn't too bad of an install, but headers can be a serious pain which can't help the install price. Even if you can find the parts cheaper, it's still quite a bit of money for the power gain. The exhaust note would be awesome fun, which factors into the cost as well, but it's not like it sounds bad stock.
That is a serious downside to Lexus... aftermarket parts are expensive.
I can add 200+ rwhp and torque to my car for less money!

RR racing has already cracked the Lexus ECU issue. So Afrosheen you need to check your sources. They have it for the RCF and now the GSF. I have seen it myself since they used my GSF to check the programing of the ECU.

So a world's first, that's pretty impressive. Is this a piggyback ECU or does it integrate?
their is not addition ECU. He remaps the mapping on the actual ECU that's in your car. They figured out the CODE and they rewrite it based on what its needs. they also Dyno the car to make sure its at peak. He working on the supercharger kit for both the RCF and GSF.
