Looking at the significantly lower peak temps afforded by the AA intercooler, I'm wondering if overboost can be set as a permanent boost target without significant risk. As I understand it, overboost is limited to short periods due to temperature concerns.

Any thoughts on this? Another way of looking at it is I suppose if anyone's running JB4 map 1 with intercooler upgrade and seeing no substantial temperature tradeoff from stock then perhaps it's just temperature management.

Most effective way is to have DME unlocked and flashed.

Alternatively, unplugging MAF sensor (disable overboost permanently) and boosting with piggyback will do too.

Factory overboost is a joke for it's off at above 4750rpm where you'll be really at when flooring it. In addition, I heard it won't be activated upon downshift.

Hope that helps.

Hmm that's even worse actually. I didn't know it switched off after 4750. What I read is that it is a 7s period. No mention of cooldown though. If it's an rpm cutoff then clearly it's a heat concern then. Will need to address that immediately... If it's hard coded in software, guess I'm tuning after installing an intercooler.

It works on downshifts.
