Spartan 275 installed - My review

[gahanna-6.4]

First, let me congratulate Spartan. I ordered my Phalanx/DD on a Wednesday and it was here on Friday. I was lucky enough to get the last unit Matt had on hand until his next shipment.

Second, let me congratulate DrewTech. Unfortunately my DD unit had a bad SD card reader. Matt worked with DrewTech, I got an RMA, sent the unit out the following Monday and it was returned to me on Wednesday. Unbelievable end to end turn-around time of only 2 days.

Matt has worked with me via email and phone to ensure it installed, well, above and beyond what I would've expected.

Now lets get to the meat and potatoes.

I have been racing NHRA/IHRA SuperGas/QuickRod cars for over 25 yrs. I know just a little about horsepower, torque and tuning. My hat is off to Matt, Nutty and the entire team for the Phalanx. The power is ungodly across the entire RPM range if you mash the go-pedal, the driveability is almost like stock if you dont. An absolutely perfect balance for a daily driver.

The transmission tuning is perfect. The shift points are exactly where they need to be to ensure you're still in the maximum power range for each gear. Shifting is very firm and quick, not like my race cars, but very very firm. It wastes no time going from gear to gear. I noticed no abnormal slippage in any gear, I did not notice it ever hunting for gears. Hang on when the converter locks, it will break the tires loose even if you're already traveling at speeds above 50mph on dry pavement. It pulls hard as far as you want to go.

Those of you who don't have stacks may want to consider it. In my testing I was able to successfully darken an entire 4 lane intersection on takeoff with the exhaust in the stock location. Would be nice to get that up in the air with stack(s) rather than aimed at the ground.

I'm most impressed with the amount of time that has been spent tuning the transmissions on these. It was nice to feel this transmission shift like it should - solid firm and quick.

I'm now a happy Spartan owner. After having both the SCT and the Spartan, I cannot recommend the SCT (based on its current release 1.26) to anyone.

Thanks again Matt, you have been wonderful to work with and I'm sure we'll meet again when I get my next truck.

Anyone had a lightning with an aftermarket valve body? I'm wondering how the Spartan shifting compares to that. My Lightning with a LFP valvebody was a little too abrupt for comfort.

Well never had a lightning, but I had a GMC Z71 with a built 4L60E from TCI with valve body, 2400 stall and stage 2 shift kit, it would break 37's lose hittin second and I can tell you this truck shifts harder

A quote from a buddy: God damn isn't this truck kinda new?

Me: Yeah why?

Buddy: Feels like the tranny wants to rip itself out of here!
