first tune, should this work

[davetheman81]

Ok so my set up is done, basically unhacked 2g maf, fp green , 850cc injectors , walbro 255, 272 cams, dsm link v3,ok onto the laptop i have selected 2g maf , i have set my global/dead time/ injector sizing, i have got my target idle perfect, 2 step is set up, and boost gauge as knock. Car drives fine but i am now putting in my aem wideband and i will attempt to boost. With the ecu basically just set up for correct injectors and maf, should i be able to run around 17 psi of boost with out knock and with out going lean?

You'll be fine.

Thank you sir, im guessing that when you add agressive boost then you really need to have the car properly tuned? And whats a good area for the wideband to read inbetween 10 and 11

Correct on high boost needing proper tuning.

I always recommend people to shoot for 11:1 AFR on pump gas.
