Built daily drivers??

Good talking with u today dan. Thanks for helping us out.
Might have to get a set of carillos from you if this other set falls thru as it is the only thing my motor builder doesn't have.

Ok guys, I cleaned the thread up and moved the dual fueler "discussion" to a new thread, http://www.duramaxdiesels.com/forum/showthread.php?t=34924, please try to keep this one somewhat on topic. I left the DSP discussion here, because I thought it was usefuel for folks running big power trucks that want to dial them back for daily driving.
At what point are people deciding to upgrade the stock cam and would it help with spool up on a DD?

I ran SoCal's 6460 cam with their upgraded valve springs and steel retainers in my motor. I can't say for sure how much of a difference the cam made because I changed so many things. It power and driveability, spooled good, and ran lower boost than several other similar setups I've heard of with stock cams. I still had stock head castings.
I'm in the same boat changed too much at once, but when dunbar dyno'd my truck he couldn't believe how fast the chargers lit. He actually dumped out of it cuz he thought it broke lol. Mine was a custom grind by bullet cams
Sorry perhaps start a new thread I'm intrigued about the individuals that can switch from a tow tune to a kill tune and completely do away with the relearn process of the Allison. I see the common denominator that we are talking about is that more than likely 01 TCM calibrations that have no fast learn process.
Maybe I gotta kiss and make up with Tony! I'm sure I'm on his shit list! :roflmao: :roflmao:

im with you. i can putt around on my third tune, switch to my biggest tune, hammer it and the shifts are perfect
Most of the issues that arise with shift quality and DSP position come from two things: Incorrect tuning and a driver that likes to do a few burn outs. Mine shifts great in any position but if i spin my tires playing around the next set of shifts will be off. It's all in the tuning though.
I never had any shifting issues when I had the DSP5. I do think the truck runs better on a single tune however.
Don't really know for sure. Mine was always a tenth or two faster with a single tune loaded. Even with the base tune as the big one.
My converter lock-up is noticeably smoother just normal driving on the big tune than the next tune down.
22,000 mi on the built engine and cracked a cut and coated piston with the 900hp tune. Not impressed at all. If the cylinder wall is damaged, I will be replacing the pistons with forged ones. I blame the injectors, won't mention the shop they're from but when its confirmed with flow testing that they are bad I will.
X2 had same issue with an LLy this summer, about 12,000 on cut and coated pistons. Injectors, checked good though.
Interesting on the single tunes set up. Still can't believe how many built motors barely last 10-20k. Kinda waste of money to be doin it every 20k miles.
My engine builder said do not use cut and coated pistons over 700 rwhp for that reason, that is why I went forged
Can someone explain why a forged piston is hard on rings? Is it the thermal characteristics?
