So I have the Banks PowerPDA for gauges and I am running the Spartan Ultra free tune. I also am running ARP's with new stock HG's. What would happen if I turn the PDA up to the highest level? Am I gonna blow the heads into tomorrow or is it ok with the ARP's? The reason I ask is I used to get 18+ mpg when I had the PDA at SL but now tuned by SCT I am getting about 14. Both hand calculated. So give me your honest opinion will it mess up my engine if I turn up the wick?
