I just put a TS cam in and built the motor it already had headers and a interchiller with 9.17 lower pulley and 2.5 upper run on 93 and E but I am down to 15% E now trying to make sure I did not have bad gas. I pumped out 5 gallons but it all looked good and I used the aux pump to pump it out so I have not tested my intank pump but my pressure seems to be good. Aux pump is a DSX can bus and comes on at 500 KPA commanded pressure. When I put the engine back in it ran great for about 30 miles and I bumped up the rpm to 5k when after the pull about 1/4 mile down the road it goes dead. I tried to crank it up but it was like the engine was locked up. I waited about 30 seconds and it fired rright off and ran fine . I replaced the batterry with a new one thinking it was bad but the next time I ran it up to 5k rpm it did the same thing again and locked up also. but after this time it did crank back up and run but now it wont idle right like its misfireing on a cylinder. I pulled the valve covers but did not see any problems., I would like for someone to look at the scan of when it shut off on me and see if anyone can see a problem that would cause this . Maybe someone that can read the tune better than me could find the problem right away. I sure would love for someone to find the problem as its run me crazy for 2 weeks now. I will post the tune and the scan so maybe someone can help me out. On the scan at 7:44:734 is when it went dead but you would only know it by the rpm going to zero.
Thanks
