I want to get a mail in flash and was wondering how much whp can i expect from this setup: Megan Racing 3" catback, M-R 3" high flow cat, 3" M-R downpipe, 255 walboro fuel pump, cone filter, and hallman mbc set to 22 psi.

 

mail in flash is good but a custom tune is better since every car is different u should be at 280 whp

 

also, if you want to vent the bov to the atmosphere, does the tune get rid of the stalling issues?....

 

Nope it does not u need a standalone in order to get rid of the VENTILATION of the BOV.. otherwise it will stall

 

how much does a custon tune run for? whats included besides the dyno pulls and the tuning labor? is anything actully installed on my car or does the car just get flashed?

 

That set up ranges from 285 - 305, the mail in is prob usually in the lower end of that range and the custom tuned on the higher end.

The flash can not help you out with a VTA bov
