I already had a similar debate in my head a month ago between Steeda UDPs and the delete plates and the UDPs won the argument for me in the end as a local guy gave me a great (and I mean great) deal on his like new pullies as he removed them to install a blower.
I ended up dropping by Steeda to get them installed which added some cost but it was a good idea anyways as I wanted them to look over some other stuff on my car which they did at the same time. Always great guys to deal with in my experiences (used to dyno my old car there and they were always nice and friendly).
Now that I have some more spare time/money I was dead set on delete plates as my next step and now I am starting to rethink it as my next mod.
Depending on who you ask it seems the following are true for both mods:
1-Either mod with net you between ~0-10HP depending on your other mods/tune.
2-When you add up the cost of the parts (used) and factor in that I would be doing the install myself they seem to cost about the same at first. (comparing a used GT500TB + adaptor vs a used set of the nicer steeda plates)
HOWEVER, it SEEMS the following is also true from what I have read:
PRO-GT500 TB -If you already have a tune for a CAI then the GT500 TB should not require a new tune (though you may not get the full benefit without a custom dyno tune..very expensive in my parts of the woods for a dyno tune.. the tune alone is more than the cost of either mod)
CON- the delete plates require a tune regardless and the canned tunes might not be very good and cost money which makes the delete plates substantially more expensive of a mod (almost x2 even with just a canned tune) than the GT500 TB.
CON- the delete plates MIGHT degrade fuel mileage and/or cause possible drivability issues in cold weather (im from canada, so days ranging from freezing cold in the morning to shorts and t-shirt in the afternoon are a real thing here during certain times of the year)
CON - the delete plates will technically make me fail the mandatory province wide emissions tests. Even though the tune from my sct will turn off the dash light for having the motor removed, I am pretty sure the OBD tests they do will see that there is no motor attached and instantly fail me.
So the way things are looking for me right now, in the game of hopefully gaining ~0-10HP....the score is:
+1 point GT500 TB
-3 points delete plates
Also since I have a JLT intake (I think its series 1 or 2) it does not appear that I would need to purchase a new silicone coupling for the GT500 TB like you would have to do with some of the other aftermarket intakes.
Taking into account that I do not have many other mods (CAI,gears,UDPs,mufflers, SCT SF3 canned Bama tunes), are there any other factors I should be considering between the 2 mods?
OR are there other similarly priced mods I should be instead considering that would provide similar HP results? Only other mods I can think of in the same price range is a catless H or X (and that catless pipes are illegal here )
Final questions/thoughts... on a lightly tuned vehicle like mine, do you think the gains people are seeing from the gt500 tb swaps are simply from the fact that a spacer is being added? I know spacers alone are not a very worth while mod, though it would be pretty funny if the majority of the gains for lightly modded cars could simply be attributed to the spacer and not the larger throttle bodies themselves.
I am also kind of skepticle of the "improved throttle response" and really to me it would just seem that whatever tune you have in the car is just not calibrated for use with a larger TB so it is sort of a placebo effect. sort of like the difference in throttle mappings between a "street" tune and a "race" tune (IE same amount of right foot just opens throttle different amount, but really the car isnt making any MORE power if all other things were equal and you were going wide open throttle, just opening the throttle more/earlier at part throttle making you think it is etc - rant - man I miss cable throttles)
SIDEBAR:
Considering the bolt ons I already have, here is a synopsis of what it is like to currently drive the car:
0-25% throttle - wow this thing picks up pretty good
25%-75% throttle - jeez this thing seems faster than I thought
75%-100% throttle - needs more power..
I am not expecting either mod to be a night and day difference by any means, just looking for something to at least help a bit at WOT.
Thanks for any insight you might have.
