Working on the Tune for my vette. Mods are as follows

Texas Speed 2.5 Heads
Tick Stage 2 Torquemax cam -226/234 | .60x"/.61x" | LSA110+3
LG 1 3/4 headers
2.5 inch x pipe
Cats
Corsa Mufflers
Ported LS6 intake mani
Vararam VR-B2 intake with power duct
60lb/hr injectors
Racetronix pump and harness

Just started on it, so working on getting things fine tuned. Id idles okay, but i have the idle fairly high @950 rpm. I haven't tuned a car before so I'm very green but trying to learn. The Car runs great at WOT and part throttle, but the off idle stuff (10% or less) is kinda jerky. Just want to be able to maximze the setup and have it run well.

I've uploaded both the image of my LT primary VE table and the entire tune, but i don't have HPT on the computer that i can access email from so not sure if the HPT file will work or what. Any imput is appreciated. I'm here to learn.

Did you re-scale your Injector flow rate table for your new injectors ?
That would be the most important must change
Any codes ?
So many mods at once can be troublesome for any tuner---
Typically Idle -- off idle--coasting down to a stop are the biggest issues
Surging dying or hanging idle
Corrections that are mainly done :
ADDING a % to the "Desired Airflow table" for idle hunting or off idle surging
ADDING 2-3* of timing to the "Base timing" both in gear and P/N
For Dying when coming to a stop----Subtract a % to the "Throttle Follower" tables either in gear or P/N ---wherever it's happening
Good luck !
