it better make some power. ill be pissed.
but its hard putting miles on my car. since last september 2015, ive put 75 miles on the car. since the tune, ive put put 15 miles on the car. i work 6 days a week, 5 of those days are in the county office, one full day of paper work.
i just hope this tune is nothing more than a fancy throttle controller.

It means the correction factors are not valid. Your dyno shop needs to longhand the calculations for you if you want an accurate number (unless they rigged the SAE correction somehow -- which the SAEs is pretty clear about) or maybe just talk to them and explain your concerns regarding the lower numbers and as it pertains to SAE corrections and their dyno. Ask them if having such a low pressure during testing is throwing things off considerably more than they're correcting for.

All mods are a risk, in-fact, in this thread two of the guys are saying their Borla didn't yield any power gains, yet no-one is crapping on aftermarket exhausts and removing the secondaries.I agree, but what results are you looking for? I assume the results that RR originally put up was not good enough for you? If you didn't read/or missed that post from RR you might want to go back. If you want a larger data pool of results that is understandable and like I said the companies should do this in-time , if they want to build trust. Still, don't ignore the fact that the tune results WHERE posted by both vendors.Yeah, the F is very finicky to mods, I remember the thread a while back about a guy who thought his Joe-z was a scam and he did a dyno and it showed no power gain. Later IIRC, he found out he had IAT issue from his "cold air" intake and the computer was adjusting timing to account for it.

The standards used for dynos are set up to correct for the majority of differences in atmospheric conditions at different elevations. As you can see we've been talking about the lower pressures in CO and how they relate to dyno numbers (if they do at all) so it's a little premature to go drawing conclusions with data that is "outside of the range" for SAE corrections.

If they're not in their corresponding threads then look in Facebook. Both companies have posted pictures and videos on their corresponding Facebook accounts. RR racing has posted videos and pictures of both, their shop car and customers car at the dyno. TTS has posted the same from customers cars since they didn't have a shop car at the time.

Guys,
I hope RR racing and TTFS can tweak the tunes for high altitude applications at least up here a Mile Hi
I have the utmost respect for Rafi and Simon as they have been awesome with great customer service the past 8-9 months since they've been on the ISF tuning scene
That being said our results so far with the tunes on both ends have been mixed to say the least. The two guys with tunes here that went to the dyno day are:
DCguy: Joe Z Exhaust/Joe Z intake/gutted primaries/ RR tuned/ dynoed @378 Whp/ dyno sheet on Pg 9/Post 125
Liquidtek: Joe Z Exhaust/Joe Z intake/ TTFS tuned/ dynoed @ 368 Whp/ dyno sheet Pg 9/Post 126
Two different tunes from both vendors who are active on this forum presently and getting the majority of the business for tuning the ISF currently.
My mods: Borla Exhaust/ HPS intake
My first run back in November netted 357 Whp & last Saturdays run netted 357 Whp essentially showing 0 hp gain
Anyhow we've done some pulls together more so with DCguy and me and you would think he would pull with the mods that he has (Tune/gutted primaries) and my car and his are dead even up to about 130ish
So when you see the results from the dyno day and not getting the numbers wanted/desired it leads to more questions than answers unfortunately
I think it boils down to someone who pays for a tune (whether TTFS or RR racing) expects to see real world results on the road (forget dyno numbers for a second)when your doing pulls with another F that doesn't have the tune or has less mods one would expect that the car with a tune and more mods would pull harder than a car without either??
Hopefully RR-racing & TTFS can adjust and fine tune the tunes for altitude (at least for our circumstances) and then the results will be more favorable.
