How exactly would it be useless? Our stock ones max out at 20 and that means I can’t go up in boost. I’m already hitting 17-20psi depending on the air temp outside so once I put my ********* on and 5 gallons of e85 yes it will definitely help me get beyond the point of throwing codes or whatever difficulties you guys go through. I’m also doing a tune on top of the jb4 so I will be doing a setup that holds a constant 24psi

I don’t know what cheap chinese TMAPs you’re running but I presently go up to 25psi on a heatsync stage 2 tune without issues.

Just an FYI for people like me who were under the impression we needed 3.5 bar tmaps to go beyond 20psi. i have a vivid racing stage 2 flash with the jb4 along with VRSF ************ *********s ARM cold air intake N63intakes oil cooler valve ngk 2 step colder plugs this is on a n63 NON TU...on map 0 I’m running 17psi map 1 22-23 and map 2 23-24psi...so no need to add these unless you are turbo swapped

You absolutely need 3.5bar sensors to safely run over 20psi. Otherwise, you're just asking to smoke your motor due to out of control boost.
