i have the same issue and i am looking into buying a Evo evolution, would i be able to bump up my idle with that? Would i need to buy custom tunes?

could you do this with an Evo evolution tuner? Do you need to buy the tunes? I have no idea how it works but im having problems with my truck idling at 500 rpm

You can do it with the canned tunes when you get the evo and load a tune it will ask if you'd like to customize settings click yes and go to idle I think with edge you can only go up by 100 rpm increments but with the gryphon you can go up by 5 rpm increments.

thank you so much i appreciate it. So i did the gotts mod, put weather stip on the air filter lid, and cleaned the air filter and man that made my rpms go up a little, no more shaking when i put my truck in reverse and slightly tap the pedal! Now i just need a tuner, i heard that if you put a tuner on, you cant get your codes pulled at autozone and i also heard that they can mess up your computer causing you to need a new motor is that true?

Mod (Ret.)

Where, oh where did you hear this?!?!?

Total bunk, provided the tune is not aggressive to the mods you have in place.

Well, put my new direct bolt walker cats on this weekend and did'nt help my low/rough idle or my hesitation and lack of power.............. Looks good though

Tons of steam? Me too. So my converters are ok?
I recently changed my warped intake manifold. Is there any way for
water to get into the exhaust from this point?

Any conclusion to to problem???
having similar issues and have replaced same parts.

Replaced my fan blade a while back because I noticed one of my blades was missing a piece. That seemed to fix the shaking/hood vibration but my idle is still low, around 580. It runs ok but I've given up replacing parts. Im sure I've done more since this orig post. My current issue is a perfect start in the morning but struggles and starts weird when driven and warmed up. Don't know if its related or not but something still is'nt right. Sorry I don't have a specific answer
