I'm running the standard non smart 93 octane v390 map. I recently bought a 10.5 hotside and a o2 housing. I will be doing a manifold also. I'm also interested in upgrading the wastegate actuator while I have it all apart. My question is, will a higher pressure actuator mess up the off the shelf map in any way (I will be using the 05 v390 93 oct map with the 10.5 hotside)? I dont think it will because the xede will see the higher pressure as higher load and compensate. Well thats what I think anyway. Anyone know the definite answer? Also, can anyone make a good recommendation for a spring rate for an upgraded actuator?

 

The higher pressure actuator will require you to drop the numbers in your boost table. Instead of the usual 90-100%, start off with 0% everywhere and go from there to achieve your desired boost. If you don't modify your boost table like this, your boost levels will be astronomically high!

....not to mention that the O2 housing & manifold will throw the AFR tune off as well.

 

awesome. thanks shiv. i did find someone running a forge motorsport wg actuator with a 10.5 hotside and the xede. said he had to cut the boost in about half. it was buried in a thread about installing one. any recommendations for one?

 

I put 2 restrictors in my stock line. 50-60% for 21 psi
