Ok, I know this has been covered before...cuz I've read about it. But I can't seem to find it tonight.
I installed an EGT gauge and a DPTuner with 60tow, 80tow and 80econo...and all three spike the EGT's with little effort. Also quite a bit of smoke on the 80econo.
I really hope the Tymar/BHAF Napa 46637 air filter and Walker BTM Napa 21470 muffler lower the EGT's (and reduce the smoke).
I read a week or two ago that the BTM will lower it by 100 or so...I hope that's true, cuz the tuner is doing me no good where it counts, pulling hills. Haven't towed yet...but I'm guessing that EGT's will be the same there too. I'm towing 2 jeeps to Moab in 2 weeks...and I hope I don't have to keep it in the stock position.
So...can anyone tell me how much the Tymar/BHAF will lower the EGT's? Also, how much will the BTM lower the EGT's?
Does anyone else get tons of smoke on the 80econo setting?
I drove a local summit (Parley's 7120') twice in the last 2 days. Both in the morning hours, 50-70 degrees. I started out in the 80econo setting, and it would just spike too fast when I needed to pass or regain speed. Modulating the throttle according to EGT's (1200 limit) resulted in lower actual speeds than the stock setting (see below)
I let off the throttle and hit the 60hp tow mode (high altitude) and it was a little better, but not much.
This morning, I kept it in the stock mode. With the cruise on 70 (75 actual) it hovered between 1100-1200 most of the time, reaching into the 1250's at the steepest before downshifting to maintain speed. Then it dropped to 1050. (tangent: it never used to downshift with the 295s, only with the 315's)
I did this for two reasons: To establish a baseline before intake and exhaust mods, and to find out what it has "survived" in the past (stock and blissfully ignorant of EGT's)
Thanks for your help!
