Request some info, please.
I dynoed the car on Friday. It seems to be a "tad" low. Maybe ya'll can give me some advice. Here are the car and mods:
94 Impala SS, LT4 hotcam kit (full cam kit), mild P&P heads (1.94/1.55), 30# inj, p&p MAF, 52mm TB, LT headers, LT4 km, SLP CAI, A4 w/ 2400 stall, 3.08 gears, PCMforless tune.

AFR steady @ 13.8

Need to get that A/F down IMO. A little lean for my liking. I try to stay in the 13.1 to 13.3 range. Thats not that bad IMO. You might be able to get up in the 330 range w/ the heads... Some cars are just hotter than others...

Yeah that's too lean. Also put a stock maf back on it as ported mafs are too unpredictable.

Yah the new maf was a waste. But its an auto auto's suck power for the mods you have with such a little cam that sounds about right.

302rwhp is very respectible for those mods, richen the mixture and it may be a little more. That car would stomp any Hemi Chrysler 300C, or most any other car for that matter. Sounds like a real nice ride you have.

the whole story does not appear to be here...

you running thru cats?
what kind of exhast?

 

[SAPPER]

I have LT's with no cats and 2 1/2 all the way out through very old and empty flowmasters. (basically straight pipes)

Here's a copy of the dyno. Unfortunately, he had mph instead of rpm. But all pulls were from 3k to 6100.
