None of the pulley pullers are difficult to use.

You can kill KR with an intake depending on your current intake setup. Also as you said, a FWI or good CAI has the ability to help kill KR. Colder intake temps means less KR. I remember A LONG time ago when my dads GTP had a 3.25 pulley on it. The car was getting 2-3* of KR depending on conditions and whatnot. He put a well insulated thrasher intake on the car and all of his KR was killed. This intake is still on his car to this day, it seems to work VERY well.

But what kind of timing?

He'* running an INTENSE standard PCM IIRC. When he hits the track, he runs 100 octane with zero KR.

Just throwing this in there...

I got a modular pulley system with a 3.4" pulley. I thought I would spend the extra money on that in case I wanted to modify my car further. I never did. For a daily driver, a 3.4 is fine with me. If I did it again I would just go with the cheaper standard pulley.

another benefit of the press-on is it looks more stock than an MPSs, the MPS looks cooler, but also doesn't have the stock sleeper feel to it if your into that

Actually that is exactly why I chose the press on 3.4 at first.
I was less than half way thru my 6 year warranty when I popped it on.

ive been thinking about doing this, too. Ive been told by a guy with a GTP that if i want to put in a 3.4 pulley, i need to put in colder plugs, 180deg therm(which i will put in when i change my LIM gasket) and a CAI(does anybody make one for Bonnies?). would i need anything else? im not gonna do much else, i want this car to last, too.

NGK TR-55 V-power plugs (one heatrange colder) gapped at .055" instead of .060".

180 thermostat (drill at least one tiny hole in it).

INTENSE FWI (fenderwell intake). Best option for the 2k Bonnevilles.

thankya.

*off topic* standard +3 degrees intense pcm *back on topic*

and my opinion is go for the mps system.
