I would definitely like to improve some of the torque I lost when I did the SRT. Any others here see a difference???

How much would tuning cost? What's going price for the Neo's these days?

If I upgrade exhaust w/Apexi catback and Megan B piple, then I might ditch the SRT/ECU and go to Weapon R or Injen, coupled with Apexi SAFC for tuning.

Several here have reported better results with SAFC if one is doing multiple mods.

General Classified. Found this one which is the SAFC II it's a older version of the Apexi Neo but does the same thing.

https://www.clublexus.com/forums/gen...nd-turbos.html

I found a few in the general classified and also try craigslist and/or ebay

It's not harmful to the engine if you get it professionally tuned/dyno if you lean out the air/fuel too much and the weather changes/elevation and all these other things that come into play will add more wear/tear on your engine. The Neo adjusts your air/fuel ratio's in order for you to gain hp and tq from your engine mods.

Depends on what mods you have installed.
