are they worth it and is there are pulley kit just foe the N/A?

 

Not too sure what you mean by a voltage kit.
If you mean a grounding kit - there are mixed reviews about them.

Pulley kits gain a few HP, but they cost $380 from Evosport.

For that money you can get an ECU map and gain more HP & TQ

 

the ecu flash will do a lot more than the pulley. the pulley, imo, seems to help out at accelerating when at really high speeds but not so much from a stand stand still. the ecu flash works across the board and it is very noticable. i use the voltage thing- seems to do what is advertised (which is very little)- not really worth the money although i see you can get them fairly cheap now.

 

Well Can You Do Both? Can You Do The Ecu & The Pulleys? I Am Thinking Of Doing The Following In June Because I Want 50hp To My N/a:

1. Sprint Booster
2. Ecu
3. Tvt Exhaust
4. Cold Air Intake
5. K & N Filter
6. Pulley Kit

How Close To 50 Extra Hp Do You Think I Will Get?

 

Well lets see
1.sprint booster = 0hp
2.ecu = 20hp
3.TvT Exhaust = ?
4. and 5. = combined 8hp
6. Evo sport quotes 13hp

look foward to seeing some time slips from the strip

 

well, i think i have squeezed just about all i can out of this engine for the time being, and i gotta say, i'm a pretty happy camper. my car feels like a completely different car after all of the upgrades. i'll have to have my first trip ever out to the strips, soon.

 

i see what you have done in your sig. whats the powerchip? is it an ebay thing or an actual ecu programming? did you get everything at once, or one at a time? what made the largest improvement?

 

Chip/ECU will make the most obvious power improvement.

 

check out powerchipgroup.com and inmotionusa.com
both do the same thing, but i believe inmotion is a lot cheaper. this was the biggest, most notable, improvement. i installed the pulley and the intake on the same day, so there was a nice improvement, but i can't be totally sure from what.

 

are you guys worried about loosing warrenty, or do you have cars without warrenty? this is my biggest hold back since i purchased extended warrenty with my car.

 

You gotta add injectors at the top of the list or you'll be stuck around 235-240 HP.


Glad to see there is additional interest in performance products.

Our exhuast is still chugging along, we've upped the quality and look and of course with every change things take longer to finish.

my car is already at 60k and i've had no problems with or without the mods. i have and extended warranty through carmax that i hope i will never have to use (good until 80000 miles). an ECU flash is impossible to even detect. they will have a hard time saying that a cai or a pulley caused any other issues that might come up. these are just easy bolt-on applications. they all come off as easy as they go on, anyway.

 

TVT - do you have injectors for sale?
If not, which did you use for your car?
Obviously the best way is to have an ECU tune done after the injectors are in, but if you were to guess what power, if any, would you lose if you did the ECU then larger injectors?

 

If you have a CAI and ECU tune already you can safely install 19lbs injectors (run at 21 lbs on our engines). If you have a CAI and no tune (17lbs), if you have just a tune (17 lbs), if you want something that is going to let you grow and still be functional (21 lbs).

If you are interested in injectors we can get you them just PM me.

 

Hey, i see that u use 21lbs injectors, where would i be able to get them. plus i just order cai, exhaust, spark plugs, and ecu and was wondering if changing my injecters would affect my HP gain
