Anyone out there using this or is the 3 bar map more popular?

 

I'm using a 2.5 map for 12.75lbs

 

Did you get it from DSteck on hp tuners forum? What are you tuning with?

 

3bar zr1 here. Works good. 15psi

 

ZR1 Map sensor for my 6.2 turbo. You can pulle sensor info right off hptuners.

 

Is The ZR1 a direct fit?

 

mine was tuned with Sniper.

 

I left the stock map in place to keep hole plugged up. You will need the zr1 map sensor harness and will have to cut factort plug off and solder on new plug. I then used the pcv port on the intake with a piece of 3/8 tube about an 1" long then plugged new map onto that. I have the wiring schematic if you need it because the wiring order is different.

 

It was plug and play on my 2012 Sierra.

 

Tell me more!

Buy 3 bar zr1, harness, cut and solder.. Is it not the same size as the stock one? Why did you relocate?

What was done in the tune? With this work on a 04 and Hptuners?

Thanks for the info sir!
