Well, maybe you guys have come accross my thread before. I'm the one with the bahbahbahbahbah over 9 psi once past 5-6k rpm's. I've changed my igniter clip, plugs (gapped @ .08) checked timing @15 deg. I have a 3" turbo back exhaust, stock ecu, stock injectors, walbro 255 with a greddy fpr set at 45 psi, swapped out two ecu's, FMIC with no boost leaks, compression test at 155 accross the whole bank. I don't know what to do.... I just wanna cry .... I don't know what to do.. I have no more money to spend on it, not even a ****ing dollar. I spent a little less then 10g's in less then a month to build, paint, wheels, controllers and other **** i never needed. Well there fun toys. For the love of god. CAN ANYONE PLEASE HELP ME. Oh yeah, and coil packs, I don't know how to check them. But, i dought it's that. the plugs I bought are the denso iridiums. If I don't get this **** running by the next week, I'm selling the mother ****er. **** it! As of now it's up for sale, i took it as a joke now I'm selling it.. Unless someone can help me fix it. I'm mentally tired. Here it is: http://www.autotrader.com/fyc/...id=57

Did you change the CAS too? or fuel filter? check the pump voltage?

You can usually visually check the coil packs... look for signs of heat swell on the sides of them... it will look a bit like a sweaty baseball cap, like how the sweat sort of discolors the side a little bit. It will still be black, but you'll see a line in it and it'll be lighter black above the line.

to do it correctly you should measure voltage accross the terminals.

Have you checked for exhaust manifold leaks? RB20's are notorious for breaking exhaust studs. Depending on how bad the exhaust leak is would influence how high you can boost and could make a strange sound as well.

just an idea...

Do you still have the cel? If not it kind of seems like you might be running out of fuel up top. Do you have any sort of engine management? If so try and raise the up top. Or if not try and raise the fuel pressure up.
