1995 GMC Suburban K-15500 SLT from North America - Comments

I was wondering if anybody knows what I can do to get better performance out this vehicle. Ever since I had owned it since 1997 it really hasn't had the pulling power. It has GM 350 and has a towing package.

Thanks for any comments.

Trade it in for one with a 454?

Larger exhaust for starters. maybe a 3" single or 2" double. possibly a new computer chip as well or secondly if the first isn't enough.
