'95 Dodge V-10 PCM Performance Upgrade

Have a '95 Dodge V-10 in which the PCM went out. Has had new factory module installed and was extremely doggy. Have carried back to Dodge three times and been assured it is set to factory specs. Have called several after-market performance companies and have been told that they don't deal with Dodge V-10. If anyone has any info on Dodge V-10 performance upgrade modules or flashes, I'd appreciate your help. Especially if you have used one and have positive or negative feedback. Thanks.
