Can't figure out why i'm losing compression?

Just wanted to share with the forum what happens when you you add a HRC Stage IV Turbo (Super 20G) to a HRC Stage III set up and tune.
I was fine with running my 20g turbo with HRC Stage III system @ 14lbs of boost until i got greedy with boost. I cranked up the Meth injection psi and turned up the boost to about 18lbs. Not a great ideal.. Trust me, it felt intoxicating and was very addicting. Could not stay off the gas! It was soo distracting wasn't listening for a ping. So much for a knock sensor to protect the motor or was it just one death defying detonation?

I guess it's too late to go with the big sleeves that Tony is using to shoot for 500 horse.

I purchased 2 LE 5s back in the day and had one waiting on standby with a now complete HRC High boost kit and some head work. This one will have proper tuning. No messing around with this one.

Ouch

Ouch. Sorry to hear. If you are interested in getting the new motor sleeved. PM me. I will hook you up with Dave over at L.A.Sleeve. They did this to my block. Should be bulletproof now.

Hey Tony, yeah i was checking out ur block and sleeves, they look sweet. I've been debating about your set up as though it is the rite thing to do. With the right tune and the upgrade fueler along with the thicker head gasket kit to lower compression, i think this issue should be prevented with my new upgraded mods. I'm stopping at 400+hp. I'm too risky to go for more.
Plus i just had a lil baby boy so i need to calm down.
