Awesome kit, how would you say the car feels compared to stock? Does it feel more torquey in the low to mid range RPMs?

Anyone got this kit on a m/t running 91/93 no fuel return? Hoping for a spring order/pick up(road trip), super curious about number for above set up.

Sounds good!

And gone is the flutter of the previous version! Greats stuff!

I have the previous kit and managed to completely get rid of the flutter sound, with this I mean, completely. No traces of it at all; and with Aaron's silencer in use as well to quiet down the "Pshhhht" sound.
I'm happy with it, but no doubt this new kit is way better.

Looking at the graphs, any insight as to why the blue and green torque curves start dropping after the HP cross while the red just keeps climbing?

Do you happen to have a plot for boost pressure?

The corresponding red torque curve would have also leveled then dropped off had the run continued. As you can imagine when viewing that graph: that particular run was stopped short at approximately 7K RPM where it the torque started to drop (the previous "blue" and "green" runs continued until ~7.4K RPM (looking at the graph, his intake popped off at ~6.7K RPM).

Well the red torque curve would had eventually dropped as stated by Northstyle. If you have more dyno questions let me know as I want to make a vid at the dyno and can asked the tuner some questions .If it's ok with Aaron I can post the link here to show the hp #s on the S/C as they are coming out.

Hell yeah man. Anyone buying a kit is free to post whatever they want. I've always been the kind of shop that isn't afraid to show whats actually happening. The more truth and data the better.

Anyone running the kit that has piped the intercooler blowoff out of the area between the intercooler and radiator? I’m looking at doing this since I’m thinking the extra heat coming from the blowoff is heating up oil temps a little. Worth a try I guess, these parts are cheap.

So if using EcuTek boost control, does it help or unnecessarily complicate to have an independent boost controller in-cabin? Considering merits of Innovate SCG1 vs PSB1.

For $40 more the scg-1 let's you dial in boost per psi. But, it's not as fast going from say a daily map of 10psi to a kill map of 17psi. Plus, you will be tempted to dial it up "just a little more" lol

What would be your purpose for having an in-cabin boost controller if you already have the ability to change the map/boost pressure via the ECU?

Because then you can literally dial in whatever boost you want from 10psi up to 20+ psi. I dont think your tuner would want to have you upload 50 maps. Do you really need more than 3 boost levels? most dont

However, I am not sure all tuners are capable of actually knowing how to control the solenoid. If they cant, then a boost controller will be required.

I mean, hell…. I plan on running 2 maps. Hi and Lo, with a flex fuel sensor…. I guess I’m mature enough to know “just 1 more pound” is like going back for a 3rd plate on Thanksgiving…. It’s all sh1ts and giggles, until someone giggles then sh1ts at the repair bill. :driving:
