Hey guys I have a quick question. I have a 2000 c5 corvette with a forged and cammed 6.0L engine. I am still running the stock 78mm maf air bridge ect. When i do a pull in warm weather (70+*) my afr stays right where i want it all the way to the limitier. The maf usually hits 9,980htz and will never go higher.
The maf table runs out to 12k htz i believe so I assumed the maf is capable of reading that high.
When the temperature drops below say 65 and i go do a pull I get the same maf readings but the afr starts running away leaner throughout the pull. My ait sensor works good, injector duty cycle has plenty left in it, has a fresh raceteonix pump and wire kit ect. I think my maf just cannot read over 10k htz and its leaning out.
I have 2 85mm truck mafs sitting around so if you guys think thats my problem I will just make a new intake setup and retune.
