Awesome!

I had 2 more questions...

Will this setup require any of those pills people use in the hose?

And how has this setup performed for people? How much have people held to redline on the stock turbo?

Thanks.

The Perrin ought to have less pressure drop than stock, so you should be seeing more boost. I'd be looking for a boost leak.

mrfred,

I've done nearly 3 tests and have found nothing. I don't know why my pressure is dropping so much. I hope the gm 3 port remedies it a little

Do most people use the standard TBEC tables once they have set the BDEL and MWDC or is it simply trial and error trying to set up the TBEC table?

Have you tried swapping back to the stock IC?

No, it was a pain in my **** to get the Perrin in, I don't want to have to take it back out, but it may be necessary to see if that resolves it.

Thanks for the idea mrfred, I hadn't thought of that.

So what 2 wires do the pig tails off the GM 3 port connect to? The stock solenoid seemed to have multiple wires in it.

should only be 2 wires on the stock.

I don't think it matters which way its connected - I followed whatever is in the first post..

I see, it must have been the angle I looked at the solenoid wires then. Thanks tephra.

Well the red wire is power and the green is ground or return. I just finished mine up and checked the voltage today.
