Its been a hard cost pill to swallow to make maybe 60+ more hp. The headers are the big ticket at $2500, and I cant find a local shop that would do any other brands due to their quality and install issues. So Im stuck with those/plugs/wires. Im also getting an IW 9.1 lower and that was almost $1k. Aside from that they are installing everything, burping the IC cooling system and adding water wetter. And also installing the TCM and tuning the ECM/TCM for 93. I already have the rotofab installed.

So total is like $8k.

They are telling me i will be out of fuel system so no E, and Im not getting meth or anything. So I was thinking.

What about skipping all of that and just putting on a maggie instead? Not doing the TCM or the lower or any of those other mods except a tune. So basically maggie and tune.

Can I not do that? Will I run out of fuel with 93? What are the opinions with starting the boltons vs just going to maggie. I'd like to make 700/700 and be done with it.

Opinions?

If you just slap a Maggie on it and bolt ons, headers, intake 103mm tb you’ll
Gain about 120whp over stock. The stock 90mm at sea level elevation your going to hit 16lbs of boost and you’ll be on the edge of the fuel system on 93. I think I made 670 with above mods. Your high side going to be tapped out completely around 690.
