maybe a little racing around at a stop light or two but mostly I just want more power. Something to either to complement the EZ or totally replace it without putting too much strain on the IP. I dont think I will be towing anything big just a 18 foot boat once or twice a year.

All i really want is some smoke when i stomp on it. I like the idea of a comp box more because of the versatility. The injectors with the EZ sounds like I could run into problems later if I do tow something. Like EGT's. My only question is how hard is a comp box on a VP? And will my 220000 mile injectors be ok with it.

Is your tranny auto or manual? Upgraded or stock? If you don't have a performance clutch or performance torque convertor/valve body, but want injectors. I wouldn't get anything over a RV275 injector until you beef your tranny up. My brother is running RV275's & a Smarty, his clutch slips when it is below 35* out. The fueling boxes are more aggressive & will kill factory tranny or clutch.

Joey, go to user cp in the middle of the screen & under edit signature, if you fill in what you have on your truck, you'll get alot less questions.

My Mach 2's will smoke some just slightly (Depending if you catch the turbo off guard...then you can get an angry puff or two).....I had a 8000# 27' camper i lived in before i got my house up here. When pulling the thing from Texas to MO on 44....highest i got on the EGT's were 1200* on a heavy long pull at 32 PSI of boost. Smoke was not an issue. Best of both worlds. NOW when i tried a MAD ECM/Smarty.....it smoked pretty good...but still controllable.

ok well now i got some info up, I cant get too crazy with power but im looking for more. All I really need to know is if a comp box or any other box that connects to the IP will be more prone to blowing my stock IP because it has 220000 miles on it. I know you have to tap into it, I just dont know how much strain that puts on the IP.

Have you read about this new Quad Adrenaline box? I like it alot more than my old Drag comp. As long as you have good fuel flow, your ip should be fine. I now agree that the pump tap will be your best bet. It will give you plenty of power, injectors only compliment a box.

Your VP doesn’t know if there are bigger (65-105ish HP) injectors installed or not. SO those would not stress your VP at all. The VP is just doing its normal thing and the spray angles and such are change to be more efficient for power. The only issue with running JUST injectors is that your truck might see the over boost and try to defuel.....mine never has and i have heard that its only a 98.5-'00 issue as the 01-02 trucks dont defuel for over boost.

The Fueling box directly taps into the VP and overrides what the ECM, APPS and such tell it to do to some extent. This is not bad...but its in all how you use the power.......

Its all in the right foot and how you use it....but you shouldn't have any pressing EGT issues, no.

I love this site. Of course nobody but me can make up my mind. It is very silly to ask questions like that. But it is fun to share and get all kinds of advice!
All in good fun. But the implied point is that you can go pretty large on injectors if you are willing to adjust to the size.

A bigger injector doesn't automatically mean high EGTs.

As far as injectors are concerned, EGTs are a function of fuel quantity and injection efficiency (spray angle, atomization, etc). Up to a point, flow can be increased without appreciably negative effects on efficiency.

So simply installing higher flow injectors does NOT mean you'll automatically have EGT problems. As I've said before, "it's not how much fuel you HAVE, it's how much you USE."

It depends on how you drive and whose injectors they are. With the F1 injectors I have, I was able to drive with VERY little smoke in hot weather in high altitude (density altitude over 12,000 ft!). I have a manual trans truck, which helps. This was with a Smarty tuner, even-- with super aggressive fueling.

Now with an EZ and stage 2 injectors (say, mach 2s at 105hp), I'd expect that smoke control would be almost effortless, especially if you do what I'd recommend and move the EZ's jumper to setting #1 from the factory setting of #3. With larger injectors, setting #3 is a waste and just makes more smoke-- the power difference is practically zero in the real world, but the smoke control is much easier.

With an EZ on #1, and some Mach 2 injectors, you'll have a sweet setup that will tow anything with a hitch and give you a solid 350hp or so. This is also within the range of an HX35 turbo, so instead of spending big $$ on a aftermarket turbo, you can pick up someone's used HX35 in good shape for cheap and have a wonderfully versatile all-around truck that just happens to have over 350hp and kicks some butt.

Be advised that 350hp is the danger zone for a factory auto trans, so unless it's beefed, you're signing its death warrant.
