    Going to pick up another 005 MAF, so I can try again to modify the fueling map & rpm limit.

    About 1000 miles on the motor since the rebuild and the addition of LH2.2

    Modified the stock runners instead - the custom required too many angle alignments at the same time to fit - I found that the runner / plenum flanges are also offset in two planes.
