Experiences with fixed pulleys?
The search turned up some gleaming reviews, as well as some complaints about issues with tunes. All of which are several years old.
Was there ever a final word? Loungn14 said that Eurocharged doesn't really recommend them but didn't give me any information.
Did every one give up on them or is there any one who has been running one for several years now that could provide some feedback?
Thanks

I can't speak for any other tuner but I have a 77mm FSP tuned by Tony Lawshee and it is perfect. No driveability issues, strong power everywhere. Only added about 5-10 degrees to my IAT's when driving and that is in 108 degree heat.
I use meth to control temps so I am always around 5-10 over on IAT's with meth on and at or below ambient when it comes on fully. With meth off I am around 20-25 over ambient, about 10 degrees hotter than my stock clutched pulley.
I do put transmission in C mode as in S mode the car spins the tires over 1/2 throttle. I love it and will not go back to clutched any time soon.
The power is addicting. I now use the edge of my foot to roll on the throttle and there is acceleration anytime I want it. Really changes the characteristics of the car as torque is on demand, no waiting.
I am all stock with the exception of the 77mm, meth, and split cooling.

Not a track car so for me there is really no need to test fourth as I value my license but I could see IAT's approaching that level on a longer pull with my stock cooling set up.

I'm running a 77 fixed, 550 injectors plus cooling support. Never will go back to a clutched. Got to give credit where credit is due, but Tony at RaceIQ, does something with his tunes that is nothing short of a miracle!
I don't see a downside and to date have never heard of any real problematic issues coming from a fixed.

This may not be advice you will accept, but tuning the car and driving it without knowing what is going on, and spending money on one thing but not having the cash for something like a WB - not the right path. Details matter. If you are in too deep, pull back.

I fully understand the importance of of a wideband but the cars air suspension went out and cost me $2000 over the weekend so it's been one thing after another. Anyway. I don't hate on your opinion and it's the right one. I may just get rid of the car. Will see. Anthony sending me a stock injectors file now. The issue is. Dealer tells me one thing what mods are there and I think it's not correct. Think they lied to me. In other words I got screwed brother. Anyway. I'll let you know how the new file runs as I just added it. I do love these cars. But wondering if the love I have for them is worth all the pennies.

I added his tune to my car yesterday and it's running awful but it isn't his fault really. I bought this car from a dealer and they gave me a list of mods it has and "they" sait has 750cc injectors, 400 lph fuel pump, 6.0 SLR pistons, and cooling mods as well. Well the air/fuel ratios are not good and it's running badly. Issue is there is no wideband and I don't have the money to buy a $700 dollar deal right now. In the past tuning software have data logging through the OBD port and his software doesn't some I'm stuck with a huge mess. It's running but is anything but mediocre. That's why I asked if you changed fuel pump or had any different mods to keep up with 72mm. How did you do data logging if any?

I didn't pull an Injector because my mechanic wanted to 2.5 hours in labor. So I just assumed stock Injectors since it was running so poorly on 750cc injector tune. The result of adding stock injector tune is much much better since Anthony sent me that. But it's still has some hickups. We are getting there. The tune is also for 6.0 SLR pistons. Which I don't think it has either. I think the engine is stock on inside (as dealer lied to me) but it does have TB 80 mm, catless, long tube Kleeman, and full carbon fiber intake. I really believe it's stock but could be wrong. The cooling is there and has different cooling pump. And heat exchanger. 72mm UDP pulley was added yesterday. It runs about 93% correct is what I had emailed Anthony. I told him it was running so bad prior that it wouldn't hurt to try to tune with stock injector ratings. Anyway it's a lot better. I will buy a Wideband within the next 30 days so I can get this thing right.

I would believe with that the injectors have been upgraded with the mods listed however I wouldn't believe the 750cc but rather the more common 550cc Bosch injectors. That is what most people install when starting to go smaller pulleys, especially if it's a 72mm and an 80mm throttle body. So I would get a tune for the 550cc injectors
