I e-mailed them and they said no LSS PCM off the shelf, and I was sure that they didn't have one for my car, partly because it'* a '96 with a 4t60-E and partly because it'* a Park Avenue.

But, their tuning software does support both of our cars, and you can register 2 cars on it, so we (me and Insane LSS) were planning to buy it.

But if you know that they have PCM'* for an LSS, tell me more.

And what were you saying about GM Tuners? Would they have a tuner for ODB-II Supercharged Series II cars? Currently I only see Series I and older stuff on their website.

I guess that he'* doing ok, considering he'* got 183,000 miles on his car and I'm sure it'* not flowing as good as it was new. If you fight KR with headers and a 3.4" pulley, I don't feels so bad. I just thought he shouldn't have any KR with his mods on 93 octane, but if he'* not the only one.

The point is that those who DID, went after it immediately. Don't sit on it.

At the very least run some Seafoam top-end cleaner to get the deposits off the valves and cylinder walls that may be causing pre-ignition. That may take away one or two degrees of KR if the deposits are bad enough.

I think that I am going to seafoam my engine

Now that I have true cold air it runs alot better and stronger
