I really was considering myself done (for now) with performance after my udp install, but I can get a reallyyyy good deal on some slightly used delete plates. I wont say where until I know if I want them or not lol.

Just wondering if they are really worth it. Do you feel the performance gain? how many rwhp do you gain?

Rubrignitz

From everything I've seen they're worth maybe 5whp above 5k rpm, if that. If you have cams, head work etc they may be worth a bit more but even when I had aftermarket cams I never ran them. Some that actually *have* them will probably chime in but I've seen many dyno sheets which confirm about 5hp.

What did you think about the UDP's? That's another thing I've put in the 'don't need' book but have heard differing opinions on them.

I have had them on two of my cars. Yes there are worth it. I don't know the horsepower gain but you can feel the differance.

Quite honestly, I didn't do mine because, before, people online would say they are not worth it.. but after getting them done, I should have got it done sooner! Great little mod for the money, not a tremendous change but still worth the throttle response increase as well as noticable power increase. I like mine

Rubrignitz -- I knew it wouldnt be a big increase, but I guess 5rwhp for $150 is pretty worth it than.

Stealth-- did you have them before or after the blower?

Nuke

I keep hearing that you lose a little in the low end of the power band but gain a little up high.

SpartaPerformance

Yes they are worth it! She feels so much smoother in the higher RPM range and no with any good tune you will not lose any power down low.

I did mine about a week before my supercharger. Honestly, I felt more of a boost from them when I was NA than with the blower. The blowers power just kills any noticable gain of the delete plates, but surely, with them on there is no power "hump". Just smooth acceleration.

Again, it's a great little mod but nothing like gears of CAI. More of an icing on the cake sort of deal.

Alright thanks everyone I am just going to get them. This will probably be the last performance mod for a while. After I get my rims, I will do my roush fasica and just going to enjoy the car this spring/summer =D

I didn't notice any lose of low end power. My 60' and 330 were about the same if not a little better with the addition of delete plates.
