truck is in the sig. with the warm temps im down from 8 to 7-7.5psi. Im getting some ID850 injectors soon and was thinking of going to 10psi. This would require a meth kit and at $500+ for a Alky kit im wondering if its worth it. I was told I would see maby 24hp going to 10psi. Should I be running a meth kit with what I have now? I dont think I will have to get a retune @ $120 just for the injectors. Mike said he will check the tune with the injectors just to make sure everything right. I assume just a data log off the dyno. I will need a retune for 10 and meth so it would cost $800 maby more just to go up 3psi.

 

Push the 10lbs run meth and retune. Smile at the extra 75-100hp.

 

He's not going to see a 75hp increase from 2-2.5 psi on that Maggie. If your going to go through the hassle and expense of adding more boost and installing a meth kit, then go 12 psi with meth and a retune. Then you will notice a big difference from where your at now and the added $ spent will show some nice results.

 

It's a 6.2, pretty sure there will be pretty close to a 75 hp gain from 2.5 psi, and meth. You gotta get rid of those cats though.

 

I agree, with both.

 

Im with Mike too. 10lb and meth plus getting rid of them cats. 75hp. I gained 50rwhp with just 2lb.

 

Adding just 2-2.5# will not net 75hp but if you remove the cats and add meth then that should get you pretty close to 75hp. I would still just go to a 12# pulley with meth and a retune. Just my 02 cents.

 

Cranking the timing for meth would net a healthy increase alone. What are cats? Lol.

 

Meth and only 10lbs ?? It's not needed. Go 10 lbs

 

wtf dude you not allowed to turn it up until I do!!!!

lol
