Reason I ask is because...

I was the first to run the -91 on my Toyota Tacoma. Underdog Racing Development made the kit with a -81 but I asked for a -91 with a larger pulley.

What we ended up finding out was that I was making way more midrange power and a peak of about 450rwhp on a less aggreesive timing map on only 9.7 psi. While the guys running the -81 trim made less midrange and took a whopping 15 psi to hit 450rwhp.

The -91 trim also provided significantly lower boost temps

Wonder if GTM has tried the -91 with a larger pulley.

The 1.5 kit does use the smaller blower but it provides more mid range torque and in my case it has also given me more hp than stage 2.

I am curious what you are comparing to? Did you try stage 2 and then go back to 1.5?

There is no one on this forum with stage 1,1.5,2 that has more power than me plus dyno results are on the forum.

Anyone with Stage 2 and the same supporting mods as you? Same tuning? too many factors...not saying you are wrong, I believe you have the highest hp but the -91 is a larger more efficient blower

It doesn't matter how efficient it is it doesn't make more power and thats whats important.

Sure it does. The -91 trim flows 11% more than the -81. You may have the record for now, but I have no doubt someone running a -91 will be able to easily surpass your hp and torque curve

more air and less heat is going to make more power. I would say for now you probably have a superior tune than others with a stage 2

I thought Jamaica was close to 550 WHP with the Stage 2 kit and he blew his 7AT then sold the car.
