What engine rpm are you at around these speeds? 1800ish?It happens when I accelerate easy or hard to anywhere between 60-70 mph. It only happens when I ease out of the throttle though. If I let out of it immediately it doenst do it really, but it I ease out it will buck my truck like crazy at times. And like we talked about, it takes a good bit to get the truck to quit doing it someitmes.
Yea, sometimes it is hard to get it to stop bucking. I either floor it or hit the brakes if its bad. Its about the best way to get rid of it :nod:I had it happen a couple of times today too. It feels like the bucking I get when I am pulling an empty gooseneck trailer on the 275 tune. You kind of feel like you know how it is to have 'shaken baby syndrome'. I think it is because of the touchy throttle. I got it once when I hit a bump. I think my foot jerked a tiny bit, which caused the truck to throttle up, which caused my foot to move again, and so on and so forth. I have found that it take a very steady foot to drive with the higher tunes some times. I pretty much always brace my foot against the transmission hump to keep it from bumping the throttle too much.
Just exactly what are the downsides?I'm with you Gerry. If you're running the 310 tune as a daily driver, suit yourself. They warn against all these things but it's just up to driver. There are big plusses sure, I agree, I love the throttle response on my 310 tune, but there are the downsides too. What do you need the 310 tune as a daily driver for anyway?
