Need Help! Lost power from the last dyno???....
Need Help! Lost power from the last dyno???.... Gotta figure out whats wrong w/ my car lost 8 rwhp and 18 rwtq after the header,TDs,ws6 airbox, slp air bellow,TB bypass,EGR and AIR removed,plugs and wires install
When I dynoed my car b4 I had just lid and loudmouth and dynoed 332 rwhp and 347 rwtq w/ my A/F ratio at 12.6-12.9
now after install of the above mods, mainly the headers and True Duals I lost hp and tq and my A/F ratio was upto 13.6/7 will this be making the big difference??
It was also performed on 2 different dynos, 1st time it was at Xotic Motorsports and this time it was at TTP. they were both dyno jets
At XOTIC I was able to do the dyno runs my self, at TTP a guy who works there did the runs....
Could there be differences in dynos or the ppl that are doing the runs?? or is it the A/F ratio???
TIA

ps the 1st dyno was back in Jan and this time is was a week ago, same temp and humidity

make sure ur not throwing codes, check sparks, 02 sensors, leaks after header install, and get a good tune. u should be putting down at least 350.
what surprises me is how high ur dyno was with just a lid and loudmouth, maybe the dyno read high numbers.

Go back to Xotic and dyno again.
You may be throwing codes with the EGR and Air Pump Delete.
I would go back and double check everything, your connections..
sensors, plugs, plug wires, TB and headers. You may have
a leak pulling in air or something.
Looks like you may be running a bit lean which will kill power.

yeah i know im running lean, im gonna adjust that w/ hp tuners and check to see what codes im throwing, i deleted the air and egr...Well i have to scan it shorty
w/ my A/F ratio being in the mid 13s how bad is that killing hp?
Thanks

Check your timing and see if the computer is pulling a bunch out.
It may detecting knock or if you are too lean you may have
some detonation. I say double check the install, fatten up the tune and
go back to the original dyno and see how things shape up.
My car lost like 9hp peak when it was 13.8 AF compared to 13.0
but I don't know how much it will affect yours?
