Hey guys new to site and turbo regals.Just had a stock rebuild on my 87 T Type done. The car is totally stock except I think the cam was upgraded not sure of specs I'm trying to get them from builder. The car seems to be loading up on fuel and stumbling down low. I have ruled out coil, ignition module and TPS. My question is going with a little bigger cam cause problems with the stock chip in the ecm.
Problems after rebuild

Possible: Bad MAF, Bad O2 sensor. Stock chip...BBKJ?

It's the chip code for the stock recall chip. It's printed on the tag on top of the chip.
When I see a 'fresh rebuild' I always cringe a little.
I cringe a LOT when I see a flat tappet cam in that fresh rebuild.
Before you get to indepth and start spending money, pop the DS valve cover off and start the engine. The first rocker to look at is #3 exhaust.
If all the rockers aren't moving the same, you've found your problem.
On a side note, if you truely have a stock chip, it needs to be ripped out yesterday. It flat out won't work right with todays gas.

Can ran fine before rebuild. Injectors were cleaned and test before being reused no black smoke on startup.
Im positive the cam is fine , but it is stock original chip. I thinking chip is the problem
The car was my dad's bought new off showroom floor. It has never had a recall chip replacement . It has never been back to the dealership .

What do you have for acquiring some data? Scanmaster, Powerlogger, fuel psi ga,?
W/o some hard data, the "20 question" saga begins.

Been using snap on obd1 scanner. We were looking at maf counts today when driving and they were normal
No check engine lights
You nailed IT BBKJ chip was in it. Just installed new turbo tweak chip and it runs a lot better. But it still feels like it is stumbling a bit. Not as bad as it was. We are going to test o2 sensors now. Did through a code for o2 we cleared it and it hasn't come back
