I was just wondering what you guys do in the way of tuning with your LSX swaps (in the So Cal area?). I swapped a new LS6 in to my 4th gen. It runs great but my LTFT's range in the 22-25 range. I didn't quite understand those before and my knowledge is limited in regards to some of this data. The STFT's run at 0 to -1 or -2 range, but mostly at 0. I recently replaced the oxy sensors with no change. I don't think it has anything to do with any exhaust leakage. I think it's just the fact that the LS6 needs a bit more than LS1 tuning.

 

you need hptuners and a wideband

 

or holley HP complete stand alone It would cost as much as the HP tuners and a wideband and has all of it and self tunes

 

I went to the Hptuners website. Ouch. That's an expensive program considering my needs. I was just wondering if anyone did this tuning at a shop or is this one of those things that CARB prohibits? I haven't heard of this Holley program before....

He's highly regarded by my LS and Impala friends. Give him a shot.

 

Is he still working for Superior Automotive? That's what the link led me to.
I can plan an LA trip if that's the case.

 

This was a fun project...

 

Sending you a PM.

 

Tad is good, Charlie at RPM motors in Santa Clarita gives a hell of a good tune too.

 

Tad heard he rushes his tunes, also can't tune autos.
