P0101 Hypertech Programming????
I installed a new blackwing intake filter system, performance exhaust and reprogrammed the chip with the hypertech for performance (canned program). I have a 99 C5 with a 6speed tranny. The performance power was better but every once and awile the motor would skip (miss) as if a lump is going through the system.
Finally, I got the check engine light and the code is P0101, Maff system performance problem. Anyone seen this before. I returned to stock programming last night and haven't had any problems thus far.
During the system mods, I only encountered one problem The duct fit where the blackwing housing connected to the system was very loose. I had to modify it with duct tape (don't worry, it was the NASCAR rated black tape) to make sure it was tight. Are there adapters for this connection from the Blackwing to the intake duct?
Any advice will be appreciated!
Thanks in Advance.
