You guys think new exhaust is worth anything as far as my ET goes? I might throw the 2.5" pulley back on there just for ***** and giggles too even though i dont think its netting me any more boost

The most I have ever saw was a spike of about 149kPa which works out to like what.....6.5psi? With the smaller pulley i would see spikes of 145kPa-148kPA at the top of the 1-2, 2-3shift, with the majority of the time being spent in the 136kPa-141kPa region. With the larger pulley i dont see the spikes with the same regularity, but have seen them in the low 140's and didnt figure the 4 or 5kPa the smaller pulley was netting me justified the warmer IAT's. I am going to put the smaller pulley on this time and really wrap that belt around as far as i can on the blower pulley and see if it makes a difference. You can see in my signature that it only looks like the belt is wrapped around maybe 50% of the blower pulley. I am going to loosen the tensioner and slide the blower tensioner pulley over to get as much belt wrap as i can. There no such thing as to much wrap right? Sometimes i worry about the belt being to tight. I have done the marker test on the crank pulley and found thats its not slipping, so im not worried about that yet.
