383 Stroker Dyno Results w/Sheet & Video! The tune is still slightly off but I had a chance to get 2 baseline pulls today for $40...couldn't turn it down. Here are the results:
She pulled strong to start but the curve flattens out at 3800 rpms, then picks back up at 4200. You can barely see it, but it spikes at 5200 and then rolls on up. We think it is a timing issue since the AFR doesnt change and the AFR isn't perfect but it isn't horrible. The VE tables need to be tweeked but we thing timing will change this number drastically!
ANYWAYS, back to the point, she put down 423 RWHP and 395 RWTQ. What do you guys think about this dyno sheet? The video is from the first run when it put down 419 and 395.

Not bad my friend.. Glad to see your build paying off.. My dyno sheet looked somewhat on the same order with similar problems.. I'm worried about the timing and how to correct that since the AFR looks decent. Let me know what you figure out with yours and good luck man..

Got ya.. My car was tuned with no knock module at the time. Since then i have put the LT4 Module in which has done wonders however, Im not sure if the timing and such is still off.. What are you seeing with your data logging so far?
