GTM Stage 1.5 s.c. tune issue

kentmo280z · 03-21-2017, 12:43 PM

Just back from my Tune on 3-20 17.

Still have disappointing numbers. 455rwhp/ 337 torque ,90mm pulley

Maybe someone can spot an issue.

First of all , My original stage 1 tune was 405 rwhp and 355 lbs torque , 84mm pulley

Now, with the Stage 1.5 kit

This kit includes 3" intake, 4.5 inch filter, 3" maf pipes, 90 mm pulley.
(Tried an 88 mm pulley also, but tuner could not get that pulley to make good power. )
93 octane pump gas.

Wondering why the numbers, especially torque are so low compared to others.
My tuner suggested HFc's ( I would have to have resonated, noise level wise) to help flow more air out. Then maybe I could use the 88mm pulley also.
So there's my situation...

Not really helpful to you but how did you get a hold of the 88 mm pulley I'm getting the 1.5 upgrade this week but he couldn't get the 88 only the 85 or 90 so I'm gonna get the 90mm also my maf pipes are 2.5 inch my tuner said 3 inch wouldn't matter

Ya, that pulley is hard to find. I sourced it through a member on this site.
I'm going to try to use once I figure out my issues.
