I think having a professional build a tune will make a big difference. What actual issues are you having? For me shift point tuning made a night and day difference.

The biggest issue is getting the charger to light. I think shift points would help but it takes quite a bit to get the turbo to fully light. I am starting to mess with the timing tables more to see if that doesn't help.

Have you pressure checked everything and made sure there aren't any exhaust leaks? I realize this is the "have you plugged the power cord in?" question but someone had to ask:) shift points really do make a monster difference for a big single.

I did a boost pressure test and got all leaks figured out on that side of things. I haven't touched the exhaust manifolds since removing the engine from my pulling truck so I wouldn't think it would be those but I will double check everything. From what I remember the engine compartment is pretty clean still.

I might try tow/haul to see if that helps out some before messing with the shift tables. :thumb:
