Hey guys, so my tuner installed a pair of Tomei 280 cams on my evo. The car started fine, everything seemed alright. However, i've read that the 280s are supposed to have a very rough idle. Mine idles as smooth as stock!! Im wondering if the cams were set wrongly? Need some advise here

I had similar issues with my 272s. I was told that the tuner could "tune out the lope" which I didnt really believe, but i guess anything is possible.

Idle speed and timing at idle can "tune out the lope". Techniques in the idle maps on the tune to keep a more "stock" idle quality.

Tomei 280 cams have a very good, close to stock, idle quality. If you would've gotten say Kelford 280's then yes the idle is really rough. But not so much with the Tomei cam. I have these cams but I havn't put them in my car yet. But I like a "lopey" idle

on my evo 8 I have Tomei 270 procams, and the idle is lopey for sure, even with it 'tuned down' to get it close as stock as possible. I think part of the reason its not a smooth idle may be due to the balance shaft delete. I did the balance shaft delete same time I did the cams so hard to say how much of it is cams.

I don't mind the lope, but I get quite a few folks asking, "whats wrong with your car, why does it sound like that?" That gets old after a while.

I have balance shaft delete also and my 280 are smooth like stock. I really wanted to get that crazy idle

You should put a video up of your car @ idle. I'd like to hear it

The stuff splattered under the exhaust is just moisture from the exhaust. The car had been sitting there for about 2 weeks. I figured this was a good reason to fire it up today anyhow. Enjoy.

I like the sound of that . I am wondering if the mivec has anything to do with the smooth idle

I have read that people with MIVEC have had results closer to stockish idle than people with 8s

My HKS 280's idle quite horribly allbeit they haven't been fully tuned yet. Im sure the Mivec helps with the idle quality

Here is a video

I like the gruff idle half the fun of big cams IMO
