ok guys I have a 2000 chevy Tahoe z71 (obs) truck runs and drives on stock tune but engine is not stock the build is a 385 stroker with crane cams 282h grind (duration at 50* 226*in / 226*ex106 lsa) intake is sdpc vortec tpi lower unit with stock tpi upper intake /runners / throttle body /injectors with the stock tune it runs pretty good has good low end tq and power but my ltfts and stfts are -30 between .800 rpm to .2800 I have been logging with the maf unplugged my runs are warmed up driving for 35/40 miles mostly highway so 50-75 mph slowly getting up to speed never going over 25% throttle I just need some help finding a good ve write up for the older ecu because I am not interested in the 411 pcm swap I know it opens up more parameters but I can live with what I have any help would be great and yes this is a custom build the stock intake was the junk spider injection and I wanted more low end tq for this truck anyhow but none the less I just need a good idea on how to set up my tune and hardware to tune the older ve table its not like the ls setups
