hey im looking to buy an A/F ratio, volts, and fuel pressure. and i was wondering if any of you know a site where i can find those for cheap. cause ive looked all over and the volts goes for like 59.95 and the A/F ratio goes for 69.99, and for some reason the fuel pressure goes for 150.00$ i dont know why, but yeah.if anyone knows any info about getting them cheaper please tell me, otherwise this is as good as it gets i guess, and i'll buy them for these prices, and wont be able to buy that new PCM
