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.

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.

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.

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.

Boost per gear gonna be more practical than set and forget solenoid duty % imo.

What would be cool is a trim knob that could tell the ECU to increase boost target across the whole map, while still retaining the boost by gear targets.

New Dyno graph. 710whp/533wtq!!

10psi, 15psi, 17psi.

What is also impressive is 453wtq at only 10psi!

Great numbers. The car that lifted the heads made 708 at 22 psi. How did this one make 710 at 17 psi? 710 at 17 psi is super efficient and for the most part won't have to worry about head lift.

We were WAY out of fuel on the 708 run and couldnt do much at that point. Also, we are definitely up against a very tough reading dyno. This dyno made 628whp on the ACE kit but 685whp on another.

As you know, there are lots of factors that determine a number on a dyno. You also know that some tuners throw an aggressive tune at a car and some tune for safety.

Thankfully we use tuners that tune for safety

Good numbers though. I'd definitely be running this kit if I hadn't gone turbo

Wow. At 10 psi this kit is making 70 more whp and 50 more wtq than my GTM stage 1 kit running similar boost. Awesome stuff.

What’d be the biggest reason for this? More efficient air flow/temps from the upgrade blower and intercooler?
