Need help TUNING L67

[jpratt]

So engine is almost out of machine shop. Getting a 030 bore and a mild head work. Going with ZZP exhaust from headers to tail pipe. No cat but using a resonator. I would like to see where else I can tweak to get more power. Is there a chip like the GN's or do I re-tune the computer, and if retuning is done then how and with what?

its not a chip , you need to flash the PCM with a new file.

hp tuners is the only current producer of hard/software for tuning L67 , there are a few used dhp's that come up also

if you go hpt do the pro , it has inputs for a wideband to drop its info in your scan real time without having to wire it through egr and has a more frequent sampling rate

lots of ways to make more power - while you have the engine out put a nice cam in it and springs like intense s1x or zzp xp
