[QUOTE="YellowCobra28, post: 4068518, member: 28345"] Hey guys, my mods are 2.93 and 4 lower, K&N filter, stock catback, KB boost a pump(at 25 for both pulls) and lethal upgrade, everything else stock, the blower is not even ported. One SCT tune was done with 93 octane, the other was done the same way but with a 50 dry shot, post maf. Check it out and let me know what you guys think. I will scan dyno sheets tonight, but let me know how I can post them here, so you can have a look for yourselfs. 1st pull, without nitrous gave me a modest 465rwhp and 520tq 2nd pull with a 50 dry shot(100 octane) gave me only 502rwhp but an amazing 670tq!!!! This was a conservative tune; 21 degrees timing and 11:6 A:F across the board and the nitrous was 19 degrees and 11:6 all across the board. Its just the way I wanted it. I thought on these 04 Cobras, that the 50 shot would give 80 to 100rwhp? How come it didn't do that? It only gave me 37 rwhp extra. The fuel pumps were not even close to maxing out and the maf had lots of room to go still. The TQ tripled gave it 150TQ more with the 50 shot. What the fu*k? The dyno dude said to bring back the car with a 75 shot because my goal is to get about 520-550rwhp and the TQ at this rate should be 740TQ if we assume it will triple again. If I get it dynoed with the 75 shot, I will let you know the findings. Please anyone that knows why the RWHP was lower than expected or the TQ was higher than expected, I'd like to hear the theory/reason behind it.
