[QUOTE="OCMike, post: 252954, member: 7013"] What is your fuel pressure at 6000 +rpm?? Sounds like at minimum you need to get an upgraded fuel pump. Also, what are the A/F ratios at 6000 and 7000 rpm? If the 42# injectors were installed after your tuning, they may not be opening up when you really need them to. Get that puppy to wide-band dyno. I wouldn't drive it hard until you find out for sure...cracked pistons are an expensive repair! [/QUOTE]
