Default 1075rwhp TT "Sleeper " Package from RPM
This is a car we did a year or so ago and it made 1022. Just changed from a ported LS7 to a MAST LS7. Car now carries the power all the way to 7k when before it fell off hard at 6100 or so. Look at the diff at 6800rpm... Over 300rwhp and trq

Car made 1073hp and 1030 trq

Here is the graph from before with the X-pipe open to now with the new heads and Boost activated cutouts.

Nothing else was changed?

Just have to ask because I've only seen them drop off that hard due to valvetrain, usually the LS7 intake will carry out to 7k without a very significant drop.

Nice power!

I agree i think it was some valve float but they heads were ported and set up by Richard at WCCH...

Any idea on real gains? I am using my stock catback on my stock TT V because I done want the loud crazy exhaust all the time.

This is like a mild to wild! But wondering if the gain is worth $600+
