Car Bogs after the TUNE LS1 gto A friend of mine installed pacesetter headers , intake , corsa cats and pulley we went to tune it because after the headers it started to have a feeling of fuel cutting off.
We took it to the Tuner and he dyno tuned it after he finished it still has the bogs he said it might be something with the plugs we changed the plugs and checked on the coils.
Today we took it again to him when he plugged his HP tuners into the OBD port it said no power so we went and checked we said maybe a fuse thing after we checked the Fuses We plugged an SCT dash scan and It worked I plugged my HP tuners and it can read the car PCM.
So can someone tell me from what might be the boggin thing in the car the Hp tuners coundnt find any DTC . While moving slowly the check engine light comes on and when we check its the MAF sensor we changed the MAF sensor and still same problems.
Please help.

Can you do some logs when it bogs. Perhaps it knock from something retarding the timing.
If you could post a HP tuner log, I'm sure someone will take a look and offer advice.

Sounds like it is time for a new tuner.
Not helping you get the car fixed,but i think your tuner needs to be let-go.
Check for burnt o2 sensor wires,i personally had an issue with my wire harness not being tied down and hit the header then melted. Cut out the bad,re-spliced and all was good.
Noises at WOT ,could be spark knock from running lean. My SS went way rich after long tubes,but each car seems different in the way they respond to mods.
I say double check wires to the o2 sensors and search for a more helpful tuner.
Good luck.
