Default TSP 228r cam help

Can someone take a peak at the log on my car, a bit of back story its a SBE LS1 and T56 engine and trans have 80k on it, LS6 heads, LS6 intake, Texas speed 228r cam, PAC springs, LTs, 60lb injectors. So when i go to start the car the throttle will hang up for a bit before going down to target idle. The PCM has a mail order tune from Texas speed for the parts listed above, i've made sure there is no vacuum leaks to ensure that it wouldn't alter the way it runs.

at the moment the car isn't driveable at all, doesn't idle correctly, when given throttle it some what hesitates to rev up, and after its been running for the first start of the day it will not turn back on unless the throttle is wide open and even at that it'll run extremely terrible. i'm not too familiar with the HP tuners some i'm hoping someone can guide me in the right direction of what could cause this issue. hoping it could perhaps be a bad sensor or maybe insufficient fuel pressure. I am using the HP tuners MVPI2

any help would be much appreciated

Since you have HP and since their (IMO) tutorials are so good I would review the idle section first. It's step by step and learn by example rather than learn by theory.

Simply google "Idle tuning with HP tuners" and it will take you directly to some very good links.

I have EFI live which is pretty good, but IMO HP tuners help on their forum is easier to follow with tons of screen shots.

your log shows 0.8-1.6% TPS at idle. the car will struggle to idle at that as it thinks you're asking for throttle. it needs to see 0% TPS to know its to use idle strategies. trying to idle in a cruise or coast strategy will never work.

attach the tune.

log also shows barometric pressure of 89KPA, is that accurate of where you live?

Post the tune. The tune might need some more work. It can range from more fuel to more Desired airflow.
