Engine/Transmission (1994 - 1998) TST plate or 370 injectors

[blackholehunter]

Hey guys, I'm thinking of doing one of the two mods in the title. I've been planning on doing the plate kit but, have seen that PDR has the injectors for sale right now. I just wanted to get some opinions on which would be better route to take and why. I previously owned a 92 that I put the POD's in and was very pleased with the results so, it doesn't matter to me if it is a little more work to put the injectors in, instead of the plate kit.



Thanks!

In your truck I would do a #10 plate, 3K's and Timing, your 6 hours away from PDR country( My Sis lives in Portland) I'd say give them a call and talk to them about it, I'll bet they say the same thing.

I agree. First a pate, then GSK, then injectors. (but that is how I did it and I don't know any better ) Piers is probably the best one to ask. (and the injectors have been on sale before, and probably will be again)

Save your money, by the injectors, and slide/remove your stock plate. You'll enjoy the results much more that way and not waste your money.

 

[blackholehunter]

I wasn't sure if maybe I would get a more linear increase with the injectors. My truck has an auto and I realize that is an issue with upping the power. I just want something that will give me a noticeable increase in power but, not kill the stock auto.

You will like the #10. Oo.

Even though your getting $100 bucks off the injectors already I bet if you called Piers' and family they would make you happy on injectors, plate, & gov. springs. Heres hoping you already have gauges. Right?

What's the big deal with the springs, anyway? Does that mod do anything for increased power/response from 0-2700 rpm or is the major benefit being able to rev to 3000? Mine goes to about 2700 now/stock - 215 pump.



Second question: If a #10 and 370s are added does the gsk become more significant for low end (1500-2500) power than it would in and of itself as in the stock scenario?

 

[bighammer]

Mine would go to 3k before, but it had NO POWER above 2100 RPM. Now it's full power right to 3K Oo. Oo.



I broadens the useful power band. (significantly in my case) I was forced to shift at about 2k because there was nothing left any higher. Now I can prepare to pass somebody at 2k and know I won't have to shift until about 3k. It's also helpful pulling a big load up a hill. There were times before that getting up to the shift point was fine, but the speed would drop too much shifting to get the next gear.



I think any truck benefits the magic of at least a 3k GSK spring kit. I bought the springs to make mine a 4k and I've installed the HD valve springs, but I haven't opened up the pump again yet. (another toodoo item )

bighammer -



I can shift mine at 2500 and there's still power to go. Maybe the difference is between the '94 and the '96 pump???

215 pump Does fine w/o springs.

Depending on your needs the GSK are not nearly as impressive on a 215 pump (=96+ 5sp) truck. It already had a decent defuel rpm. RPMS move it up but for a towing rig it just moves it into a high EGT area that would not have show up w/o the springs.



Hot rodding, racing, sled pulling or not wanting to add more fuel (stock plate) then GSKs are great. If one is pulling alot and just needs a little more the get from 3 - 4th with those big loads, a plate will do the same. 3GSKs with a stock plate will let it pull out to 3200 - 3400 in a 96+ 5sp. This gets you at a much higher RPM when you grab the next gear. Higher RPMS are probably easier on the drive train.



Auto trucks, older 5sps would notice a more worthwhile increase from GSK kits.



A #10 in 96+ 5sp adds allot of fuel but "nice thing about plates over injectors is you can tune the power down or up to suit your needs" (... a quote from the Piers staff).



I think all those that recomend GSKs first have never driven a good running 96+ 5sp.

I seriously disagree with JJW. I bought my truck knowing very little about the CTD's except that lasted forever and were tuff as hell. Unfortunately I bought my truck with 33" tires already on it and when hooked to just an empty 20ft low-boy gooseneck I was constantly having to shift back and forth between 4th and 5th gears because my truck "ran out of umph @ 2200rpm. "



Now as stated above by bighammer I could run my truck up higher than 2200rpm just fine, but it has absolutely no more power.



Once I slid my factory plate full forward (after I got gauges) I had power to 2500rpm, but I also had higher EGT's.



After I finally added the GSK though my truck pulls hard all the way to 3000rpms, and I don't have to constantly shift gears while towing to keep my truck in the powerband.



That's the whole purpose of the GSK is to broaden the powerband, the purpose of a different fuel plate is to give the injection pump more fuel.

Re read what I said....

Don't take my above comments to mean a GSK does not help, it is just my opinion that a good plate in a 96+ 5sp will give more then the GSKs alone and at RPMS that are EGT safe.



I hotshotted trailers with a stock govenor springs for the first 200K miles. Any limitations I had with stock power were cured with a #11 plate. No need for high RPMS if you have enough power to pull at lower rpms.



If I did not like what GSKs do they would not be in my truck.



I just notice in my truck with just a #11 pre GSK I had ZERO EGTS issues WOT, or pulling 30K loads and it pulled very strong up to 2600. Maybe more, but I never had need to run past that RPM as it was high enough to make the next shift. After adding just the 3 GSKs I could pull past 3K but EGTS became an issue and I notice a drop in lower rpms power (maybe related to #11 plate as the #10 made it all go away.



Again... if someone is stock and just wants a little more to keep from down shifting a different plate (not the stock plate slid) would do a better job then GSKs in a 96+ 5sp. This is JMHO which may or maynot agree with your needs or setup.

I installed the 370s first as there was a good deal on them at the time and was not real impressed with the HP gain. After the #11 plate it all woke up real good. The 4K GSK was after all the other stuff and as jjw mentioned was a minor improvment but worthwhile, I would do that last if budget was a concern.
