So i got my bullitt dynoed at carcraft in MN this weekend on the dynomax. It put down 229/269 1st then 231/270. Sae corrected. at 14.2 A/F. Ive got a JLT cai, SLP catbackl and diablo sport tuner. I thought id put out more since all you guys seem to get better numbers stock. It was around 85 degrees out but, i dont know any input would help. Thanks

Do you still have the stock midpipe? If so, that's alot of restriction. You'd see a few more hp by going to an aftermarket midpipe. More so than just a catback anyway.

Oh, and different dyno's will provide different numbers. even if both are SAE corrected. Alot of things factor in unless you are running back to back on the same dyno to get an actual comparison.

Ya i also have the stock mid pipe. Does it hurt the hp numbers when u get a catack but keep the stock mid pipe?

Hurt as in impacting the numbers negatively?
Most likely not because the catback will still allow for a little better breathing.

Hurt as in not allowing you to get the most out of the catback?
Most likely yes.

honestly...hand held tuners are a waist imo...if you want a tune have a custom tune done its worthless otherwise as every single car is different in its own way

DITTO-GET THE TUNE DONE ASAP BY A COMPETENT TUNER. 16 hours of training class, and "I just got this software." does not qualify.
