wssssshhhhh POW!! OH SHT...
So I rigged up an inline resistor setup on the ICM signal line to a switch. Fooled around with a bunch of different resistors. I started with 12K then 22K then 33K. Low to mid range power definatly increases with increased resistance even at WOT. Nothing seems to add power on the top end at all. You can hear it's making more boost but it doesn't pull any harder than stock.
So I decided to hook the 22K and the 33K inline for a total of 55K!!! Gunned it in second gear and flipped the switch. Very nice pull. Rode it up to about 3300 RPM then POW!!!! Very loud pop coming from the left side of the engine. Lost a ton of power, would barely down shift. Got it home and looked under the hood. The down pipe had blown off from the intercooler. Thank GOD thats all it was. Needless to say my heart dropped when I heard that sound. Hooked everything back up and it runs great again. Just gonna keep the 33K inline and call that good. WHEW!! I don't have a boost guage or EGT gauge so no idea what those values were.
I do have a question. Is there something that limits the ammount of boost on these motors. I'm thinking thats why I'm not making any more power on the top end.
