RE: 1.7 rockers
You mentioned that you are getting a turtle to help with the low end... i wonder if there are other things to do with the stock intake to help that out. Has anyone tried a ported intake manifold or heads? Could be a nice alternative to an aftermarket manifold that loses low-end torque.... its just a thought...

RE: 1.7 rockers
The M1 swap is an excellant choice. No plenum cover problems. More room to reach distributor and back of engine. Lose a little on bottom, but gain up top. Relocate air temp sensor to under TB. Powder-coating adds a nice touch it.....B&G has a reflash for this mod, highly recommended...

RE: 1.7 rockers
Ya, i've learned that most complaints about the M1 causeing low end loss are because the truck still has the stock PCM. If you reflash the PCM to adjust for the new intake, there is no low end loss, no need for turtles. I'm definetly going with an M1 if my plenum needs repair.

RE: 1.7 rockers
Whats the cost of the PCM flash? ANd do you know the turn around time for them to get it back to you? I already have the hughes kit to fix my plenum, but if i go with the M1 ill sell that to someone.
Any recommendations on who to get the M1 from and for how much?

RE: 1.7 rockers
Ok since we are on the B&G subject. I am wondering if the flash is still compatable with a Programer. Mainly for different fuels, tire size, top speed, rev limit options. Reason why I ask is becuase I run two different size tires (for now) winter/summer tires, and the tire size recal is a nice option, and since I already paid 240 for the programer.

I think im gonna pass on the M1 and flash... its a 4x4 and im rarely up in the higher ranges (though the flash will fix it).... plus, i dont think i can see the advantages of spending $700+ on the intake. (flash and M1 plus gaskets) . Im gonna do the plenum fix and drop in the roller rockers.
Do you notice a change in idle with the rockers? more of a lope because of the higher ratio? Im just curious....

RE: 1.7 rockers
I have read some who say the it sounds a little different after installing the 1.7's, but most say it sounds the same. Definetly not like the lopeing sound you get when you put in a cam. Mine are still sitting on my workbench in my garage, so I can't say for sure. I hope to install them soon, but something always seems to come up.
shott,
I have wondered the same thing about my Hypertech. I am going to be getting either a Mopar PCM or the B&G flash to replace my Hypertech, and have wondered if I could still use the code reading ability and tire size adjuster components of the programmer. I think as long as you do not install the performance setting stuff, just the tire setting components, you should be able too. I think on the Hypertech, it is possible to do just one component at a given time, but I still need to read the instructions to know for sure. Which programmer do you have? Have you called the manufacturer to see what they say?

RE: 1.7 rockers
Main reason for the B&G flash is to raise shift points. The pcm will adapt to the increase in air flow. The M1 is supposed to pull all the way up to 6k, so if your shifting at 4.8k you're not really getting your money's worth. Bottom end loss is about the same as with a K&N CAI. The reason for the loss is decreased vacuum signal. A turtle decreases the intake's volume to counter this, and also supposedly helps to direct the airflow into the runners better. If you already have a CAI with a cotton filter, you probably will notice no change in low end torque, so I hear. Weather permitting, I will know for sure tommorrow.
