Thanks for that information. How much timing would be safe down low on E85 at 25 pounds?I ran Arts 16930 with my 6262JB. It was tight on Erics default settings...you could get out and run faster. Dropping the low gear 02's to 770's and adding 6-8 degrees low gear timing it was a whole different convertor. Spooled instantly and hit full boost instantly. This was with Erics 110-112 race chip. I didn't race on the street so a tight convertor is my preference for DD and cruising.
