My car wont make more than 10-11lbs of boost (JB4 Log Check issues?)

I think he's saying that the boost looks normal so if you actually feel a difference it's likely from something else.

I was going to delete this and just stay out of it instead but can't see a delete option on my phone.

You could use IAT spoofing within the JB4 to crank boost up. But looking at your timing advance and corrections, I think it's all tracking as it should be...

Well right now my timing is shite, so hopefully going to a different station will solve that issue. do you know what the recommended brands of fuel are?

 

[Terry@BMS]

Just run the best fuel you can and use the logs to evaluate differences. When in doubt add octane booster or E85.

My state doesnt sell e85 at all, so octane booster it is!

@Terry@BMS one last question, what would you gap the HKS M45iL Spark Plugs to? Thanks

 

[Terry@BMS]

For any plug we suggest 0.022"

0.22 it is then, Thanks Terry!

Adjust your FF/wastegate adaption on your user adjustment on the jb4. Set it to 25. I had the same issue. Now I get 17 psi of boost. That will only work if you have the wastegate wires for the jb4. It's purchased separately for 140 well worth it. Good luck. Also I run it on Map 2

I have some ewg wires but don't exactly know what the ff/wastegate things doo per say. any chance you could explain them a bit or redirect me to a thread that will help?
