when to do imrc's

[stangnut]

at what point in your modding would this be the next step? i have done the gears-4.10's longtubes,h-pipe and exhaust,underdrive pullies(steeda) mgw shifter, c&L cold air intake and a dyno tune+chip. are the imrc's next? don't want to do something to hurt the performance. thanks guys:beer:

good question, I haven't gotten that far, but i'd like to see the answer.

Im going to say before the tune

 

[Cookieman00x]

Yeah I would do them before the tune you'll pick up more after a tune..

i might live in the sticks,but i'm lucky enough to live about ten miles from the only dyno in the area. car was tuned when i added the cold air kit and before i added the exhaust which i'm still in the process of finishing. i will get it tuned when the exhaust is done and after any other major mods i'll have it done again! so back to my original question, am i at the point where deleteing the imrc's would be the next logical step?:shrug:

When they are gone you will need a tune so do them now.

He's done custom tunes already, Im sure he knows that he need's that. I think his real question is he's done X amount of bolt on's, would IMRC's delete be logical as next mod. He doesn't want to loose any power.

I'd say now's a good time to delete the IMRC's and do a short runner intake. PM NaSVT. He's the god at making SRI's

do it, as soon as any one buy a sn95 cobra they should ditch the imrc's and get a tune. bottom line they are junk!

 

[1badsvtcobra]

but wouldn't that hurt the low and mid range?

it's all in the tune man

Exactly, I actually GAINED midrange power after I deleted mine because of the tune.

I've read alot mixed things about this mod, that its a great way to get the engine running better, and that its nothing but problems. Could someone clarify both of these arguments for the sake of me and the OP?

I know of no one that has had problems after deleting IMRC and getting a good tune.

As for the reduced torque in the low and mid-range, once again, it's all in the tune. Some tuners will just turn of the IMRCs and do nothing else. Timing must be added below 3250rpm, torque/power will suffer if it's not added.

This goes the same for short runner intakes also, fail to add timing down low and torque/power in the low/mid range will suffer.
