94 Impala ss ls3 from 2010 Camaro SS with 6l80e DOD delete spring rods from btr long tube header ported intake
Octane?
Take a data log for your base tune, then work on your fuel and when you get everything working properly start adding timing 2 degrees at a time (to be safe) and I prefer to reach up to 24-25 degrees of timing ( DO NOT put that timing without looking to knock sensor reading every time you add 2 degrees on timing table).

93 is all I put in tank and original injector that came with motor
I would start with 15 degrees of timing. And as Abdulaziz mentioned don't advance the timing more then 2 degrees at a time.Originally Posted by bartaponte

15 degrees won't start and stay idleing and 13 degrees is stock it a big cam I'm new hp tuners I watch YouTube and 25 degree and up is good for big cam just wondering if anybody had experience with btr stage 4 Cam
Oh you meant the idle spark timing.....18 degrees should be a good start and as you said you can go up to 25 degrees of timing. It depends on many aspects such as the base airflow and rpm.
What else should I move up it seem to idle now but when I push gas pedal shut off
Post the tune and log
94 impala after exhaust2.hpt
Do a log
Is rent trailer, bring to a pro an option?
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
