Can't dumb-it-down any further. NVM.

I believe most here don't think this is a good idea without other modifications first. I think an 83mm and tune is what is recommended. I would do a search and ask Race IQ if that's who you are going to use.

I think it makes more sense financially to have short pulls on a 77mm pulley, until you can divorce the cooling systems, instead of spending money on a trivial 83mm w/ tune, then getting the cooling mod done, then going down to a 77mm.

M5 LOL

do LTs, bigger HE and pump before you ever do a pulley. you'll be faster than a 77mm pulley only car.

99lightning

you think so?

C_Note

they will be about the same imo. Cooling doesn’t help with power, it helps maintain power. LTs or a 77/80mm will net about the same gains from what I’ve seen.

I’m on an 80mm fsp with Raceiq tune. No problems with heat soak and it runs a little warmer than stock, 3-5* on average. I will move to a 77 when I get LTs and they drop boost

C_Note

Exactly… not much difference except the LT car will probably run a lil cooler and make less boost. A modest pulley, up to date cooling, and tune won’t hurt these cars at all, as long as it’s healthy to begin with.

How do you define an 'up to date cooling'?

Mr Bike

The original post was deleted three days ago, as I never asked for any advice regarding pulley sizes / headers / cooling upgrades, etc..
None of you have a clue what's already on my car, or what was asked in the first place.

Yet, here you guys are throwing out a bunch of blah, blah, blah, even though the original post is long-gone. Amazing. Have fun with it.

C_Note

at least the latest intercooler pump. Everything else you’re adding is a modification, ie; secondary cooler, trunk/under hood tank, and split cooling. Those are mods imo

C_Note

What you asked is in the title… You should stop complaining about ppl trying to help with something you could have googled in the first place… you’re asking about tunes for a basic pulley, come on down off your high horse, talk, and listen.

real clever… good luck with your endeavors

This guy is like Toadster from back in the day.

You asked about 77mm pulleys without any other information so everyone here trying to help gave their opinions. Why didn't you list your modifications if you had any? Questions answered can help others in the future. It's not about you.

Lastly, if you are so knowledgeable why are you asking such a simple question? Why didn't you just do a search?

Good luck next time you ask a question.

Wrong, numb nuts. The whole question was about ECM tuners and ECM tuning, and nothing else. YOU quickly derailed the thread by your Chicken Little reply. "Oh no, the sky is falling! Don't put a 77MM pulley!!"

The fact is you're someone who can't read and respond in an intelligent manner. You don't even run a 77MM fixed pulley, so you shouldn't have replied in the first place, Get it?

Fountain35

We aren't in elementary school. Grow up.

No it was about a 77 mm pulley and a tuner when swapping out to a 77 mm pulley. They go hand in hand.

No the thread wasn't derailed. The fact just about everyone had differing opinions on the question indicates you didn't explain yourself very well.

Those are big words from someone who started the post off with numb nuts.
I responded just fine, I'm not the one tossing out immature name calling and attacking other members.

You don't have to run a 77mm pulley to know what works.

I and others on this public forum can respond as we see fit.
Get it?

Here's a thought. Try governing yourself like an adult like the rest of us.

If you were an intelligent individual, you would've left out the aspect of '77mm' and then no one would've commented on it. Whether it is is a 77mm or 83mm is pointless to include if you are simply curious about tuners, and tuners only.

And judging by your name calling and attacking of the community that you seek help from, it is safe to say you aren't as intelligent as you like to think you are. An intelligent individual would've been able to communicate in an effective matter that doesn't include attacking others.

Dont feed the troll guys, let's just move on from these type of attention seekers

Best tune would be who ever communicates with you the best. Race IQ is pretty good, Eurocharge as well and both have been known to have very good tunes. I use Tony from IQ myself and will say communication is important because you want someone to be available if there are any issues or questions.

drothgeb

Right now I'd recommend Vano V-Tech, for one reason. I have tunes from EC, Race IQ, and DTK. The only tune that didn't do the 82mm TB hiccup issue is the DTK tune. No matter what I did/tested the RaceIQ and EC tunes had the issue. DTK was always responsive and good to deal with but he's gone now(RIP). I haven't used V-Tech yet but plan to, specifically because chatting with some other friends who were in the same boat, the V-Tech tune also resolved the 82mm hiccup issue and I've heard nothing but great things about him, including the best blocked off bypass and fixed pulley tune supports.

Also Race IQ and EC re-tune prices are pretty high now.... and as most of us continually mod, and never stop... because that's our nature, that's something to consider as well. (I don't know what V-Tech charges for retunes)

Granted my experiences and info are a couple years dated. I don't know if RaceIQ or EC have progressed with the 82mm issue or tuning for the newer modifications, but that's my 2 cents.

black06c230

The hiccup thing has always confused me. I have never had an issue with it and have been tuned since 2014 by Tony. I love him bc is local enough with a 2hr drive and communicates with me quickly. He has tuned my modded E55 to 564hp and 666tq to the wheels, my G63 and GLS63. Those each just have catless DPs and tuned. The GLS next year will get larger turbos and a few more mods like meth injection. All will be done by Tony.

In the end communication and a good relationship are key. Jerry at EC and I butted heads long ago and I moved on from him and ever looked back. Anyone can give positive and negative on anything but what matter is your experience.

M5 LOL

OP is a bozo.



My car is DTK650 with an 82mm TB and no hiccups, and the car runs like a rapped ape. Its a shame Dimitri passed, he was really on to something.

ArmoE55

OP - you don't need a tune for 77mm. Run it stock, trust me.
