Meth injection is NEVER a bad idea. Ever. I can't even explain how many times it has saved my engine. I pinched my wastegate diaphragm changing springs and pegged my 30 lb boost gauge and didn't notice it right away. No idea how much boost I actually hit. When you're 15:1 lean and running 30 PSI with 10:1 compression showing almost ZERO knock, something saved your ***. It wasn't the junk pump gas I was running, either.
I did start with 7 psi and now 13 psi and 14* ,I am thinking of increasing the boost to 18 psi maybe but I am worried. what do you think ?

I took the heads off a month or so ago after running 30 PSI a few times. Pistons were perfect, rods were straight, head gaskets looked new.

Another question guys what ecu did you guys use, also plan on using a 4l80e and I know I'll have to replace the rear end.Is there anything small you guys can suggest I get that I may not think about?
I swapped to an 02 truck pcm on my 98 Camaro. Use efilive with a custo operating system and tune it myself. I'm not much of a tuner but have a friend who gets me a nice base tune and then is very simple doing small afr/timing adjustments. And I'm also running a stock 80e and the PCM controls the shifts making it very street friendly. I drive 16 miles a day to work. Engine is a stock longblock lq9 minus JFR 221 cam and pac springs with an on3 78/75 turbo. Makes 690 on e85 and 570ish on pump gas.
