I've compared the intakes mentioned; the SPT and the Cobb. I was planning on purchasing one of those two except the K&N was more readily available. The only differences I found between those intakes and the K&N was that they reuse the crinkle bent plastic tubing while the K&N replaces that portion with a mandrel bent pipe. Could the reason why I'm having the boost concerns be caused by just this? The K&N Typhoon intake is just a short ram just the same as the other two and with a heat shield as well.
I changed my AP map to the (STG2 91 LWG) and it seems to have first of all reduced my peak boost to 17.8psi. Also without actually staring at it while driving at WOT cause I'm the only one in the vehicle; the boost doesn't seem to jump up, go back down again and then climb back up again with the RPM. Is it possible that this has solved the concern? Was it really something to be that concerned about also? What were to happen if I left the boost to spike up to 18.4, catastrophic engine failure?
BTW, anyone have any thoughts regarding my hopes for headers?
