Forgive me, the title should be "LS2 MAF Max'd Out"
First I'd like to thank Chris for helping out with the speedo problem on the 2005 C6. Since I have the car back, I decided to get some more HP pulls on the dyno, The AFR is very nice between 12.0-12.1 the whole way to about 6200rpm, then it starts leaning out finally arriving at 12.9 at 6900rpm. I'm thinking the MAF is being Max'd out (having seen this happen a lot in S/C Fords), the scan shows the Hz exceeding 12200hz (limit of the High frequency MAF table) at about the same rpm as it starting to lean out. Hz at the 6900 rpm is 12800hz or so. Enclosed are the Scan File and Tune. I tried adding fuel above 6250 through the PE table, but it had no affect. Any help would be appreciated.
Mike
