I have a '22 M4C (3000 miles) coming this week. I was thinking the JB4 would be the best hp-for-the-money place to start...just to wake things up a bit.
Do others like the product and upgrade, or is there a different option that's preferred?

Jb4 is best performance for money trie and tested

You can even get custom map

+1 for the Jb4

if you do not plan on sending the DME to Finland, the Jb4 is the best starting point for more power

If anyone wants a custom tune for map 6 on the JB4 tuner . You can email me at sirpolly@aol.com. It is very dialed in and will get the most out of the tuner. You must be on E30+

JB4 is a great first mod

given that it's your second post here, I recommend you share some of the maps you created so customers can feel at ease getting their cars tuned by yourself

I just joined not to long ago. I got a custom tune from Eric , he is pretty well known. I definitely understand why anyone would be hesitant. But if anyone is interested there is my email. I’ll share my logs on map 6

Im confused

are you the custom tuner and you are asking customers to contact you if they want a tune? or you are just a customer and you want to share your custom map that you got with other people?

I’m not a custom tuner, but a custom tuner sent me a custom Map 6 . Sorry for the confusion. I paid $200 for the tune . I’m willing to share for $100
