You joking me?? Were lucky to have Cortney Green here one of the best in the US....

 

Cort is the best, and he is an awesome guy. I will be getting another tune through him once I get my bbk full.

I would hold out for him.... lol I remember when he was working for Modern garage, He was only putting down 490 and everyone was like WWWWAAAAAHHH!!! hahahah **** was nasty.

But anyways If you want a tried and true PRO TUNER , call Mr Green.

 

Lots of posts here about why the car may be down in power.

Possible problem:

Piston or cylinder 4 is showing lower psi. and that is not normal vs the rest of the cylinders.

Take the plug out, look inside that cylinder.

If you can get a Borescope, that is the best way to see what is going on inside there.

Look for oil and wetness on that piston.

With that much difference in compression on that cylinder compared to the others (17 to 23 psi difference), you probably have damage at the edge of that piston.

Damage to piston is almost allways the case with very low compression on one or 2 cylinders.

Number 2 or 4 usually are the ones to get damaged first.

If there is damage in one piston, the valves could also have damage.

You can loose 100 hp with that sort of problem.

Look into it.

Best of luck.

 

Yeah I have been good friends with him for years he is a great guy

 

Green is good, but from what Ive heard extremely expensive and booked out for a while...

 

Good luck my man. That car should be a beast.
