checking back for results?? and 270 at the wheels!! no wonder my truck feels so d*mn gutlessMy truck made 278 RWHP and 560 RWTQ on 37 inch tires on my chassis dyno when it was completely stock. I have only dyno'ed it on the 275 tune and made the numbers in my sig. Maybe if I can make some free time today I'll load the 210 tune and strap the truck down on the roller to see what it makes.
