[QUOTE="ultraspeed, post: 14135962, member: 128806"] I would suggest putting another waste gate on the other bank only on one side like that could really hurt things! Also the 4v does not have the issues like the 2v does on valve springs stock valve springs with stock cams will hold just fine. It can really only be a few things 1.) weak firing 2.) wastegate 3.) the tune I would start adding another Waste Gate to get even production from both banks , then a Boost A Spark.. Or get a good datalog of the car and let us see what the tune is doing as that could be a issue and I also agree from earlier id be running a tad richer on fuel 11.6 11.7 just for slight comfort. Also what was the timing at start of boost and end of rpm? [/QUOTE]
