Hi, I installed Kelford stage 1 cams with higher lift and duration on Landcruiser(2007) 1FZ-FE engine and I also Have piggy back ECU(XEDE from Chiptorque) I tuned it on Dyno with AFR Sensor, before cams upgrade I had 190hp and 348nm, after cams and remapping I have 217hp BUT 335nm

I tried many times but torque did not come higher, is it correct? or I made a mistake? (I can edit timing, TPS and MAP with this ECU) attached you can see the maps after cams upgraded.

What Lobe Separation Angle and Lobe Centerline do they have? The old ones and the new ones

what is your afr? what is the support mod can you give us a complete mod list, you might want to increase the compression as it might be too low most people i know mill the head about 1.75mm with cams

just curious im planning to get a cam for my 1fz-fe how do you like this cam how does it idle does it sound stock can it pass as sleeper? how much of a difference did it feel on drivability and wot

It's not unusual for a higher revving/higher power set of cams to make less low or mid range torque.

I change the Piggy Back to stand alone Haltech 750 and now happier It is 80% smooth in idle and works well

in medium and high rev

I upgrade my throttle body from 70mm to 90mm

engine sounds great and I have 220WHP

in stock it was about 150-160WHP
