It's very easy to install. You just have to download the tune from Bullydog's site and reprogram your ecm, however if you don't have a lift pump or a built trans don't bother. A stock trans will never hold up to that tune. The extreme setting is 138 hp and the Crazy larry is supposed to 230hp. The Crazy larry tune is the most erratic tune I have ever seen though. Hope this helps.

I've ran it on mine b4. Terrible driveability. Feels Slower then extreme, but this must be due to the lack of fuel it is getting.
Super Super High EGT levels also. If your looking for more power then extreme level I would go to EFI live or PPE

It is very very noisy. It has was too much timing rattle but it does have plenty of power. If you can handle the noise it is a nice tune.

X2. Have had zero problems with mine. No lift pump and she fuels fine, still have the slight black haze to prove it.

Oh and I am an Ex. PSD guy so the noise does not bother me at all.
