Base Tune help

[tntransam]

Good morning guys. I am very new to HP Tuners and still learning a lot about tuning these cars. I come from building Subaru's and they seem to be quite different. I have rebuilt my 99 TransAm with a couple extra goodies but am having a bit of trouble with startup idle. The car wont just start and idle. I have to hold the gas open just a touch until it warms up a little then gradually let off the gas until it comes down to idle. Once i do that it will idle fine while driving and coming to a stop and such, but if i turn it off and then try and restart it a few mins later it does the same thing.

Anyone willing to look at my base map and give some pointers that might help?

Car has the following Mods
243 ported heads
LS6 Intake
TSP long tubes with Y-pipe
BTR stage 2 Cam 227/234 .614"/.576" 113+2
BTR dual valve springs, valve seals, retainers and locks
New LS7 lifters
Yank 3000 stall

Add to your base running airflow and see how that works. Turn COT to disable.

Cat over temp, it appears you removed the cats, i would add air to the 68-284 area add 2 g/s to start with you have to view the table in metric otherwise it is pounds per hour

Thanks so much for the help. That seems to have done the trick. I need to find someone to tune the car for me.

install a wideband and get some data logs, read about tuning. i'm still learning.
