06 lly/lbz van tune wanted

I am building a 1947 Federal truck with 2006 Duramax/4l80e Chevy Express van. The harness was reworked by Standalone Harness. The ECM was sent to tuner for tow tune and EGR/VATS delete. Everything installed and ready to go. Engine starts and runs for 2 seconds and shuts off. Scan tool shows the VTD is still active and sets EGR codes. I don't think the tuner I paid did anything to my ECM. I have been reading this forum and others, thinking I would tune the ECM myself. I've concluded that it is not cost effective for me to tune one vehicle. So, I am looking for an experienced and RELIABLE person to install a tow tune (400-450hp) and delete the VATS and EGR. The truck will be used for show and towing a car hauler.


MODS:

Upgraded exhaust manifolds, up pipes, 3" down pipe

Water /air intercooler, custom intake

3.42 gears, 40 inch super singles

Delete VATS, EGR, Fuel pump relay, air intake heater

Did you ever get tune as I'm doing same in a 73k10
