This is as much as a gauge for me as it is a game for everyone else. I will be dynoing my truck in the coming months and would like to see what she's doing with the mods. Upon tuning day, I'll have a K&N CAI (modified to hitting around 5 degrees F over ambient), 160 T-stat, efans, stock exhaust, and a PCMforLeSS tune with a retune after a drive around. Anyone wanna take a stab at my RWHP in March Houston weather (no idea on DA, but it probably sucks). I'm aiming for 400HP, but that'll be easy after headers and H/C.

Can't make a guess with out knowing what kind of dyno you will be using. Will it be load bearing dyno - mustang/mainline etc., or will it be a dynojet?

I have almost the same mods including tune......I would say 345. 400HP is not going to even get close. Plus my 342HP was done at PCMForLess shop and it was almost 100 degrees ambient air temp in the dyno shop.

No idea on the dyno, it's one that billhillytim knows about on 1960 (north side of Houston). Looks like I'll need to do a bit of research... Yeah, 400HP is my end-all goal with headers, etc. I'd LOVE our truck to make that with easy bolt-ons, haha.

336 pending the dyno. if its a mustang or dynojet. mustangs tend to under compensate.

Haha, guys, I stated I wanted 400RWHP with bolt-ons and H/C and headers. I know it's unrealistic, I just want to see what I can get with the current setup. I'll hit 400RWHP someday, but that'll be after I get a different trans and a stall.
