You likely won't need the meth but would want it as a small safety net.

Make sure you verify the tuner is not using it for the fueling aspect of the tune and spray it behind the IAT IMO.

Start small and watch your wideband to adjust jetting.

Meth for only 6 lbs? I wouldn't go through the trouble of buying/installing/tuning a meth kit with only 6 pounds of boost...


That being said, you should install a meth kit and bump the boost to 15 psi :D

Biggest concern is static compression ratio with boost. 11-11.5:1 on stock pistons

I had a alky kit on my car running the p600 blower. I used it for a small safety net and to lower my Iat's. The Turbo Buick boards have tons of info on the subject.

Oh, I didn't know you had that much compression.

I had 8 psi (twin turbo) on 11:1 compression (speed-pro hypereutectic) with meth. Ran 122 mph trap speed in my 4200 lbs Caprice... but it didn't last very long:

I mean technically idn what the compression is to be honest. Le2 heads milled .010 and cometic .040 head gaskets with stock block stock pistons

Similar to what I had.

If it plays knock knock jokes it is what it is I guess.

Keep your AFR between 11.5 and 11.0 with the meth and do go crazy with the timing. I'd shoot for 24* to start.

Absolutely go meth. There is no downside, it can only help your motor last longer. I credit meth for letting mine last for over two years so far. 10 lbs on a stock shortblock.
