[QUOTE="amel666, post: 4487178, member: 64044"] Hi bros, Need some opinions here.. I recently installed a pair of adjustable cam-pulleys on my GSR. Everything ran like a charm till recently, on approx 30-50% of throttle once the rev reach 4000rpm's the needle starts to go haywire as it jumps up and down constantly but functioned normally, sometimes. I also notice that the car felt sluggish when this happen. The engine seems hesitant & not smooth at all during acceleration. Only during WOT or so does it behave normally (RPM needle x bounce) but still it isn't smooth as before. Now i'm at 4deg. advance [intake] & 4 deg retard [exhaust] ... is this the culprit or is it the other ghost(s) in the machine?? Running on e-manage blue/stock cams/adjusted-a-bit pulley etc. I know a standalone (haltec plat 1000) would really help, but cant afford one yet. :bawling: :bawling: Thanx for ur assistance. [/QUOTE]
