What's wrong with my 1LE
So I recently had a BTR stage 4 cam installed with all the supporting valve train mods and what not. I also have stainless works 1 7/8 catless longtubes, npp, CAI, scoop, and a vmax ptb. There is a drivability issues I've been having and can't seem to figure it out. Under low rpm the car will hesitate, backfire then go. I can't seem to replicate it every time but it still happens quite often and is much worse when cold. Not sure if it's a bad afr, spark plugs or what but it is definitely not normal. I was hoping to get some opinions on what it could possibly be because I have no clue.

You didn't mention anything about the tune. Usually the things you describe are tune issues.
What do you have for a tune? Sent from my SM-G935V using Tapatalk

Have you checked your MAF to see if you have a strong or weak one?

I wouldn't drive it anymore until a datalog run was done at light throttle acceleration.

I figured out the backfiring! One of my spark plugs was not firing properly. I swapped it out and everything is running perfectly now.

Mine does that too after my BTR stage 3 install. I have the NPP, CAI Inc CAI, Kooks LT and catless too. Mine does the same thing, sputters/stutters? kind of between 2000-3000 RPM and in usually 3rd or 4th gear feels hesitant and backfires upon acceleration. I am bringing it to my tuner this saturday to do some data logging and see whats going on.
I will tell you what happens and what he says unless you guys have an answer for it, or if its normal.

If any tuner claims it's normal, better find a new tuner quickly.
