Heys guys, I know there are some fast L's out there for the gen 1 but I thought I would share what my truck dynoed before and after some mods.
When I bought the truck it 218,000 original miles on it and it had no cats with a dual inlet/outlet flowmaster muffler. It dynoed 206 rwhp and 286 rwtq.
Since then I have 222,000 miles and added some ASP blue anodized pullies, by-passed the smog pump, and changed the muffler to a magnaflow dual inlet/outlet (built in x) muffler. It dynoed 230 rwhp and 314 rwtq.
Thats a gain of 24 rwhp and 28 rwtq!! Not to bad for all those miles!
1/4 mile wise it went from a 15.8 et with 16 degrees timing to a 15.2 et without the smog pump delete. I will try her out next week to see what it will gain without running the smog pump. The pullies helped out alot and I highly recommend them. :beer:
