so i today i finally got my car on the dyno and my first pull the car makes 238 hp and 288 tq. i have stage2 w/o toys and mbc runing 20psi and down to 16 by redline. also have mopar cai and a full turbo back 3in exhaust. and a safc 2that was not pulling or adding any fuel. the best pull i could get was 245 hp and 309tq. and that was pulling 15% fuel across the entire band. but according to the air fuels on the dyno at 4300rpm on up the car went complety lean and didnt even register on the af scale. wtf:mad:

sounds like youre having some tuner issues...or you have a fuel delivery problem

[LilSrt161]

the guy doing the pulls said the car just fell on its face at 4000rpms, should i try upgrading the fuel pump and go from there. also he had the exhaust probe in the right side tip which hardley flows at all, would this have anything to do with this, the guy who owned the dyno also said that the filter should probably be changed but he didnt bother for me:mad: just for the cobra

[N2MB]

were you doing a tuning session or just doing the 3 pull w/air thing

[LilSrt161]

i paid 100 dollars for an hour on the dyno, i was allowed to tune in between pulls

[Slwboy]

sounds like you need a fuel pump at a return line kit

He should be have that to run that much PSI safely

[johnnyfive]

I'd say you definately have a problem I got 268 hp and 320 lb ft. of torque and I was only running 19 psi with it falling to 13.5psi at redline. I had stage 1 with stock injectors, AGP WGA, crane 14's. I ran without an intake (pulled hose off compressor inlet).

but wow. did you install the new injectors with stage 2? are you on completely stock fuel for stage 2?

[Eulers Ghost]

I agree with what everyone is saying about having a problem. I ran an SAE corrected 253whp/27Xwtq with PCM controlled boost on S2/intake/catback/crane12's (dynojet). I dont know if you need to invest in more mods, but rather try and sort out why what you have isn't working in concert.

[jmdodgesrt4]

don't know, sounds weird to me.my 05 with no fuel upgrade yet hits 265 hp at wheel and 290 tourque..only running 17 psi with no drop off, should be able to hit 20 psi with fuel upgrade and 280 hp and 340 tourque like my last srt4 with 3 psi fall off by red line

[60-trim]

make sure you have fuel press before you tune again,check your vacume lines and do a boost leak check with a 255 and stage 2 injectors you should make alot more power...also do you no what load they had on the dyno,makes a huge difference in tunnin if the load is to high your a/f will be fucked,if you need a hand call the shop or i can just dyno it if you would like

[spoolinmopar]
