I have a Dinan stage 5 tune in my e36 track car. When I compared Dynos, my A/F ratio got too rich. I sent the graphs to Dinan for them to address and they wanted $500 to fix the tune? Why? I already paid?

After many emails back and forth, they wouldn't fix my issue. I find this pretty poor customer service and proved their software claims are wrong. I have over $30K in Dinan products on 3 cars and still git a big FU from Dinan to solve my issue at no cost.

Went to AA software, took my Dinan badges off all 3 cars and sent them back.
