Default Performance chip for LS400? What's the best first mod?

Are there any out there?

How much do they cost?

I saw this on EBAY:http://cgi.ebay.com/ebaymotors/Lexus...QQcmdZViewItem

Looks generic to me?

Hopefully there's something better than that?

I would like to get a little more out of my LS because I would like to put in on par with the 98 engine. Anything out there that I could do in a moderately cheap way?

I want to GO FASTER

Does anyone make a chip for the LS?

not a chip persay but you can use a Split Second FTC or Apex'i SAFC to manually control the Fuel and Timing.

I guess this is the way to go?

Thumbs up

The Apex'i works well, I've seen them installed on MB's to get more out of them. Seen about 14-17rwhp on average. Not bad, it just tricks the MAF freq. Simple device, you need a wideband O2 or a dyno with one to adjust properly.

Also, hack the air intake box. That will free up some topend HP (3200rpm on up). It'll also sound GREAT at full throttle.

Syn oil will free up a bit too.

only thing is that the SAFC needs a decent bit of wiring and you will drop about $200-300 on GOOD dyno tuning (w/wb 02 rental)

best intake mod is going to be the JBrady intake, just search for it.

New exhaust plumbing...there are some posts from jbrady that are good reads on this subject. This would be a good first step IMO.

I so agree...nothing quite like springing a surprise on someone.
