any of you guys are running the meth injection? not the water/meth injection (because thats for babies) haha just kidding.
My question is, i want t run meth injection but my friend that tunes my car is insisting on getting a stronger ignition system since the spark needs to be stronger to ignite the meth. Im already running the Buick Grand National coils and dont know if i will need to upgrade if im gonna be running about 35-40psi on a holset hx40 :gotme

you'll be fine, it'll have to be tuned with the meth, buddy of mine had a meth system on a stock sr ignition system and it was tuned/running fine.

i wouldnt trust a meth kit with 40psi to deliever what you need... maybe on a lower boost/power level..

I used a meth kit on my honda and it makes just over 600whp on 28psi and meth, i wouldnt wanna push it much further than 125whp past the safe pump gas limit... but thats just me
