I currently have my car tuned decently for idling and running without boost. I am going to be getting a secondary fuel rail and fpr soon once Ive saved up another 500 dollars. Am I ok letting the engine get to 5psi before shifting with my current setup even with tuning my microtech rich for the 2-8psi range or will the air that my 60-1 be too much for the factory 850's. I was planning on getting an ebc first then a wideband, then the secondary rail before getting it tuned for max hp. I would think that the 60-1 shouldnt be pushing more air than the twins do at around 10 but I dont know for sure. Any comments or suggestions appreciated. I currently have the microtech boost cutoff at 10psi just in case but not sure if this is enough or if I should lower that number as well.

 

no one yet.. am i being too cautious

 

You can never be too cautious if you dont know your AFRs and your IDCs.

I'd say you'll be ok at 5 psi, but I wouldn't push it beyond that.

 

How do you know the 2-8psi range is rich without a wideband? EBC should be 3rd on that list. You can't run a 60-1 even at low boost on a stock twins tune( if thats what you're doing), it will be completely different. I've seen engines blow @ 5psi before...

 

your ecu should tell you if youre reaching max injector duty cycle.

 

where in the microtech does it tell you the duty cycle?

 

There are 4 screens in the center, one says M sec. However thats not going to tell you if you're motor is running lean in boost.
