The 87 Performance tune has been reloaded to Pegasus. Return the truck to stock and connect to Pegasus.
You're getting awful close to stock in your timing curves......it may be time to check and see if you need plugs or coils because the increased cylinder pressures with the advanced timing puts more of an electrical "strain" on those systems.
