Heard the Piggyback ECU took away some power from people instead of gaining some. Kind of scared now from the piggyback and standing away from it. Now for the pulley i heard it gave good gains and costs way less than the piggyback ecu. Can someone tell me how much power im going to get from the ecu? and how much should I expect from the Pulley?

 

the piggyback comes tuned for a RA with basic mods. if you dont have at least intake, axleback and maybe even the pulley id wait. when you get this it is suggested you get it dyno tuned to get the most out of it. It also will help increase power throughout the RPM range better then the pulley but the pulley will see higher maximum gains.

EDIT: IMO get the pulley first, then piggy, then header or intake manifold.

 

If you can afford the piggyback, get the piggyback. Having a tuned piggyback will make 10x the difference that the pulley will make.

 

+1 to otter and the piggy. The pulley is a known and absolute difference. The piggyback is used to tune the car. It is not a power mod, it is a tuning mod, and you can get much more power from tunability than you can just bolting something to the car.

The base map is supposed to be a better map than our stock map. Unless you go to the dyno and have the piggy tuned to your specific needs then you will never be "safe" using it.

 

The RRM tune only seems to be for their intake (with exhaust). If you have an Injen intake, you will need to get the piggyback tuned. I believe this is due to the wider diameter of the injen pipe right from the IM whereas the RRM intake uses the stock intake section where the sensor sits. I have injen intake and the pulleye and my the RRM tune was way off for my car. Tuning gained me 20hp/22 tque through the mid range and 11 tque peak. The pulley is a solid, proven mod - you can't go wrong there. The piggyback will however with a proper tune get you much higher gains.

 

HEard the piggy was..... Listen to Otter and Dan they know. Other people are just starting unfounded rumors. Getting a little old now. Piggy is a great power maker and will give you power accross the power band . Period. Call us for detail of listen to experience guys on the forum that have been here for years, not newbs that say .... I heard. They are often competitors un cover.

ROAD/RACE

 

Have a whole list of mods SRI, pulley, full exhaust, etc. and barely needed to make any changes to the stock map. great mod and it comes in handy, just think if you're looking for more power now some basic boltons like the pulley would come first.

 

Here's a printout of my dyno sheet. My mods are piggyback, RRM pulley and Injen CAI. The blue line is with the RRM stock tune and the red line is after tuning. (he said it was a bit lean and tuned between 12 and 12.8 AFR). We did one other run that yielded peaks of 161 whp and 162 tq but this was a better overall tune. As you can see there's pretty significant gains to be had from tuning it specifically for your car. I see this as a positive. I really like the piggyback as a mod. Agree with DangerousDan and Otter - "properly tuned", it's a great mod for bigger gains.

 

to add to this thread...
just last night i got to install my piggyback...

the connections are perfect...idle/learning period was perfect...

now when i try to compare performance to before the piggyback...
sometimes im like "yea for sure its alot more boost in all powerbands"
but there are other times where i feel like my car isnt all that much faster...

i only have a aem sri in addition to this..
one thing for sure is that the intake seems to be making more "vrhooom " sounds more often at a wider power band...

also my gas consumption seems to be improved...

in terms of gettin the piggy tuned professionally... i dono...ill do that only if my car starts acting weird,,,like some guys have posted...

 

Get Both.

A piggyback is a good mod with their maps but can be made better if you want to tune your car. Getting a wideband is essential to tuning. I would not be surprised if a RA with all the bolt ons before piggyback and then after to pickup 15hp/tq.

 

i just put on my RRM pulley. the only other mods i have are RRm intake and apexi safc. i haven't had my car tuned with the new addition of my pulley but my dyno'd at 162.8hp/165lbtq. The pulley put on 3hp and 4 lbtq. i imagine with it tuned i would see maybe 165/168. The pulley is pretty sweet. thanks again RRM.

 

amax how come the two runs look so different in terms of curves?
(im new to this whole dnyo chart thing)

i can see that the red line (newly tuned is more maximized than the blue from rrm)...

 

That is the whole point of tuning, byc. You lean out the rich sections of the air/fuel curve and richen up the lean sections until it all meets at the target AFR, usually 12.5 to 13.2 for pump gas depending on your desires and tuner.

See how all the valleys are much smaller on the fresh tune? This is were the values in the piggy were changed. Adding more fuel or taking it away changes the power output for the range of values you hit while in wide open throttle.

RRM has copied a pdf from split seconds website onto there website if you want to learn more. You can access it either from RRM's piggyback pages or from split seconds website. The pdf is called u-tune, and is very useful.
