I know I'm in the wrong site but this site seems to be were all the info for programming late model GM cars.

I have a 1999 Chevy Tahoe w/5.7L Vortec which is a similiar setup to the LT1.

I currently have

Air Aid intake - http://www.airaid.com/200-102_chevy.asp
PowerAid Throttle Body Spacers - http://www.airaid.com/200-520_chevy.asp
Granatelli Motor Sports - MASS AIRFLOW SENSORS
CraneCams -HI-6 Igintion w/lLX92 Coil
Hypertech Programer
Exhaust- coming sone!!!

I would like to get a programer that I can do custom setting I have found this one http://www.carputing.com/ And wanted to know if there is something better or eisier?

What is autotap? Is this something good to have?

Thanks
John

 

Nothing is available yet for your OBD2 truck. Tunercat is working on a OBD2 release soon but I think cars will come first before the truck version will be released. One thing you can do is to replace and repin your ECM with a 2001 PCM and then use LS1 edit to tune the truck, but given the lack of performance that is built into the intake system doing such a expensive conversion would be hardly worth the money.
