upping the jets on same tune? I have a grudge race coming up and am considering changing out the jetting on my dry kit to a 125 or 150.
I know this is pushing it, but what do yall think? Is it safe to do w/o a tune?
FWIW, The car is fully tuned for the 100 hit.

What does fully tuned mean? The motor will take 150 the fuel system should take 150. The question is always is the tune right. if its right for the 100 its not for the 150. wheres the timming at what do the plugs look like?
You need to pull more timing. As for the spark plugs, what do you have and what gap? I wouldnt spray without at least pull more timing for the 150. What tune do you have? hp tuner full tune or just timing pulled/wideband tuned?
I saw you have a dry kit, so you should get a full retune with hp tuner for the 150 and call it a day. If you already paid for a full tune, it wont be too much $$$..This way, youll know if your injectors/fuel system are big enough and if everything is good to go.

I am not on the stock injectors. I have enough injector and an aftermarket fuel pump for 600+rwhp.
I had my car dyno-tuned by a professional. I will just have to go back and get it re-tuned for the 150 hit.
Thanks guys
