Been 2 years since a full head cleanup put the beast back in shape. Now Im stumped. Lately its been breaking the tires loose at light part throttle in 2nd and even 3rd ( rolling at 50 mph!). Thought the traction loc might be going out but there are two nice, clean, even rear tire marks in my driveway, so that's not it. Nitto 555 315/35/17s on the back. Its getting really hard to drive it on the street. Last dyno run was 4 yrs ago and it did 525 tq from 2500 to 6300, flat as a pancake. Any ideas? If the tires are the likely culprit I'll junk em in a heartbeat. Otherwise I have no idea where all the new torque is coming from.
