I have a 2010 srt8 and I'm looking to get a custom dyno tune done for this thing. My mods are as follows... Bwoody CAI, billet tech catch can, 180 tstat, 18# radiator cap, Borla type s exhaust. Everything was installed by AJ @ Westbury Jeep about 2 months ago... So I went to him last week and asked him when he could do a dyno tune and he said he has no time right now and that he's not doing them and doesn't know when he will start doing them again. So I have 2 other options, one is going to Ralph & Johns in Brooklyn NY but the thing is they only have a 2wd dyno, or taking it to Enzo in Bayshore NY who has an all wheel dyno anyone have any experience with these guys? And from everyones experience besides the numbers being incorrect what else would be the cons to running this truck on a 2wd dyno? Any input would be greatly appreciated. Thanks

Do the AWD dyno, if you like the shop there shouldn't be any problems. Dyno's can be expensive so you might end up calling MHP for a custom email tune.

Good luck.

Come to Ditos Motors in California ... a $190 cmr tune is hard to beat.. ;)

AJ is booked solid right now unfortunetly. He doesn't even have time to do minor stuff. I ended up having to find my own misfire and swap my own plugs, and now have to wait 2 weeks for a stupid weatherstripping change. I'd still wait for him though. Ralph and Johns is awful. I was gonna go to them and was told straight out by the guys at DiabloSport not to. Enzo i have no experience with.

I would avoid a 2WD dyno. Running these trucks in 2wd has a tendancy to destroy the transfer case. Theres slip, theres heat and the clutches burn out.

Right now I have one of AJs dyno tunes on my truck. It really needs work though, because it knocks like crazy. We were supposed to have redone it a few months ago, but it never got done. Our schedules just didn't mesh, and now I need to do some engine work, so theres no point in doing it.

My record run was done with one of Johans Email tunes. Johans tune feels alot stronger then AJs, but with no dyno proof, I'm reluctant to tell people that normally.:eek:

Fyi.........


(copied from johans post)
i have been asked this alot and here is breakdown on what i like to see as far as pids go in order to properly adjust a calibration.
I split it up in the two different groups for 05-06 and then 07-up and they are grouped by the groups they are listed in predator/trinty and dataviewer.

a/Getting your original backup file(Your tool must of taken a backup before this step can be done)
Click “Get Tune File From Tool”, then click “Yes”. Make sure you pay attention to where this file is saved as well, keep the name or rename it, your choice, just keep the file extension intact.
b/Getting your Last tune written file(Your tool must of written a tune file to your vehicle for this step to work)
Click “Get Tune File From Tool”, then click “No”. Make sure you pay attention to where this file is saved as well, keep the name or rename it, your choice, just keep the file extension intact.
c/ Attach either or both files to an e-mail and send it to your tuner and please include a COMPLETE list of modifications.
2/Installing one (1) custom CMR tune into your Predator/Trinity.
a/Save your tune file from your tuner somewhere you will remember and do not change the file extension.
b/Make sure you have your original backup file saved on your PC as well and know its location.
c/Click on “Send Tune File To Tool”, then select the tune file from your tuner. You will then be asked for a base file, (this is your original backup file) so pick your original backup file.
d/ You should see a quick progress bar, then a “Download Complete” box, click “OK”, that’s it, now when you go to your vehicle you will have an additional Custom tune menu inside the Performance Tune menu.
3/Installing two to five custom CMR tunes into your Predator/Trinity.

Datalog driving instructions:
NOTE: Unless instructed otherwise, always allow your vehicle to fully warm up before doing any logging, min recommended ECT temp 170 deg F.
NOTE: After installing tune, allow roughly a day for the vehicle to fully go through its learn cycles before datalogging unless otherwise instructed.
1/ Idle(mainly for head/cam and vehicles with aftermarket injectors)
a/30-60 seconds in Park then 30-60 seconds in Drive, do it all in one log. Do not touch the throttle!
2/Cruise(mainly for head/cam and vehicles with aftermarket injectors)
a/Daily driving, try to drive normal and allow vehicle to shift through all the gears while recording.
b/Steady cruise, allow vehicle a steady cruise (cruise control can be used if the roads are fairly flat) at about 55-60mph for 30-60 seconds.
3/WOT
a/Try to perform the WOT logs when your IAT/ACT have come down to normal operating temps for the best results. The temps should be pretty close to ambient. 10-20 deg F over or so.
b/Allow vehicle to shift through as many gears as possible during the run, runs that go through the 4th gear will give the best and most useful data for your tuner as that will put the highest load on your vehicle.

Attach the log files to an e-mail and name the properly and send them to your tuner for review.
Make sure to tell your tuner about any condition that you feel noteworthy mentioning, idle surge, stumble etc etc…

And always obey posted speed limits J
