These are my mods 3.5 pully,104 autolite plugs,cai cone in box,zzp 1.0 pcm.What shouls the gap be for my plugs.
 


.060 i believe.

You have no exhaust mods?

You need at least a downpipe but your best bang for your buck would be a set of Speed Daddy headers off ebay. $200 and call it a day.
 
Needs exhaust mods.

Sounds like you followed ZZP site in saying that what you bought is enough to run that pulley. We see KR from the factory, adding more boost without exhaust flow doesnt help anything.

And 104's are too cold, try some 605's.
 
You need an Aeroforce Scan Gauge to monitor Knock Retard.

Its a must if your modded.

You got two choices.

1: Put the stock pulley size back on (3.8)

2: Buy a downpipe, plog, or headers

Or you can keep your 3.5 with no Exhaust mods and watch your engine go boom.

Here you go, to help you out:
Racing Manifold Header Exhaust Grand Prix GTP Buick Regal Impala Monte Carlo 3 8 | eBay

Aeroforce - Aeroforce Intercepter Scan Gauge #

ZZPerformance - ZZP Downpipes #ZZ-GPDP

ZZPerformance - 304 Stainless Power Log #ZZ-304PLOG


 


The first two links i gave you, should be a must buy, hands down. You can also look around this forum in the "For Sale" section to buy some of these parts used to save a couple bucks.
