Popping when maf is plugged In

[black heartbeat]

just as a btw I check alldata and according to them. The tps sensor output is supposed to be outputting approximately .6 volts. hope this helps. Also I doubt it would be this big of a difference but could you be putting a MAF in with a ram air tables rather than a "na" one?

Alldata? And the new used MAF came off a 97 Camaro. I have some mechannics comming over either today or tomorrow depending on what time I get off work, they're gonna run a scanner and set the tps and check AIC

Ok here's an update I got the x pipe dumped in front of the a axle then I took it to B&R performance to get tuned on the Dyno I'll let you guys know if I have any problems after the tune

Well got bad news the tuning shop said That popping was a miss and is pretty bad and would not be able to tune it until it was fixed so they will be diagnosing and trying to figure out what's going on with it prob for the next week or more 😡

One thing you really need to do is check the fuel pressure...

I've seen a car run better without the MAF, due to the speed density part of the tune commanding much more fuel than when using the MAF tables.

Verify you have solid fuel pressure and go from there.

Here is an update the car is at the shop still and they still have not figure out what's causing the miss they said fuel pressure won't cause it to miss It's gotta be something else personally I don't think they know what theyre doin lol but yeah, does anyone know of any shops that are good with ltx cars or anyone that will work on it I'll pay whatever
