bossting and 3 bar map

If you boost above 15 lbs with the stock map sensor and stock fuel pressure and stock chip are you really gaining anything? If data master doesnt detect any knock is it likely that you could blow your motor?

you cant boost above 14.7 with the stock 2bar, a 3bar is required to adequately adjust the computer chip values.

IMO, if you are not showing any knock and the o2's look good I don't see why you couldn't run a "tad" more boost than stock. It's detonation/knock that hurts a motor. Maybe the stock chip runs a little "fat" when WOT and leaves a little room for error(more boost :lol: )? Just watch for knock. Avoid it at all cost! Feel free to correct me :2cents: :2cents:

I ran 18 psi with stock everything without any problems.. just added a little more fuel via afpr

2bar only see's 14.5 and can only make the needed adjustments for spark and fueling up to that point so it's not wise to run more boost without keeping a close eye on things via datamaster

Re: bossting and 3 bar map

you can cheat if you have a afpr and larger fuel pump and larger injectors, but if you have gone that far get a recalibrated chip for a 3bar and then install it. a lot safer than playing above 15lbs waiting for your motor to start ' Knock Knock Knocking on a Rebuilders Door
