2001 Pontiac gt/gtp swap

[lowkeyo369]

Hey folks here’s the info I have on my car. Car is an L36 block, top swapped (L67 supercharged top end for higher compression), NIC cam, poly motor mounts, 160* t-stat, thrasher fender well intake, aluminum coolant elbows, zzp stainless headers, zzp stainless down pipe, emissions deleted, stainless Borla cat back, high flow fuel pump, perfect strut towers, halo headlights, led taillights, led light conversion inside and out, functional F1 hood, F1 spoiler, 40th anniversary roof rails, GXP brakes (large drilled and slotted rotors), zzp tuned motor/trans, zzp 3.4 pulley, aftermarket gauge cluster, 04+ leather interior conversion 2" lowering kit on 18" wheels. Custom hood and bumper grill inserts, fully loaded with heads up display, sunroof, and heated seat, aftermarket long range key fob with remote start, trunk popper. New brake pads, new equss oil pressure gauge... Does 140mph and gets 25mpg average. The issue in having is. The battery started to die about 2 months ago. And with me traveling for work I was not able to maintain it. Since then it’s developed a misfire. I check the wires and those fell into pieces. Replaced those and the plugs. Coil pack module and have gone through 3 MAF sensors. Everytime the car starts to build boost it dumps a bunch of fuel into it and starts to mis fire. All live data scans lead to Low frequency MAF. I’ve replaced it. Few times and still the same issue

Any CEL? Are you using an OEM Delco MAF or an aftermarket one? The aftermarket ones are known to not work well (if at all). I got my last MAF from a JY and it's been just fine.

You have a top swap, battery issue, misfire, and MAF issue. Can you expand on each one to eliminate a bunch of variables.
When was the topswap? Was it running well and tuned after the top swap?
Was the battery or charging issue addressed? What is the voltage at idle, running, WOT?
Expand on what you saw with the live data and the MAF. OEM, aftermarket, reman, not stock, etc

I’ve run out of time to repair it. I have to rent a car and go back to work. When I took the car to 2 separate shops they both told me the MAF Was bad. I replaced it twice both with the same issue. When I asked them what the live data was saying they said everything check out. The car was running great before the battery started to die. I took it from Mi to Alabama and back multiple times with no issues.
I’m probably going to send it to ZZP and see if it’s worth saving
