So I took my 2017 Corolla iM 6MT on a 4550 mile road trip from WA State to New Mexico and back. I took the scenic route on mostly back mountain roads. Over this past spring and summer, I've installed many modifications. I installed a DC Sports CAI and ceramic 4-2-1 header, a DNA 2.25" exhaust, Quantum Solenoids, JET MAF, short shifter, Tanabe lowering springs, Tanabe front strut brace, and TB chassis braces.
I was looking forward to this trip to experience the difference. I took a similar trip when my car was bone stock so I had a good baseline. I haven't had the chance to get my car on a dyno yet but the difference these mods made was very impressive. Above 3500 RPM my iM now pulls very hard. I was shocked at how much better it did at elevation, even above 6000'. I drove over many passes that were 10k' or higher and it pulled the steep grades much better. It's like my 2009 Corolla S Turbo 5MT, but it could hold a much higher speed up steeper grades than it could when stock. At 70 mph in 4th gear at 4k RPM it would hold the speed on steep grades and made driving the mountains so much more fun. I didn't use 6th gear in the mountains if going uphill. I drove it as a 5MT unless going downhill or on a flat section. It pulls harder from a stop and was worth every bit of time spent installing the mods. I'm very happy with the results.
